Chapter 1 INTRODUCTION 1.1 General Information The Spiricon, Laser Beam Analyzer, Models LB A-300/400/500/700/708/710/712/714PC, is a low cost, PC based product for use in modern Pentium generation personal computers with high performance PCI bus architecture.
f) A high resolution color monitor. g) Windows ® 2000 or Windows ® XP Professional operating system with at least 64MB of main memory. h) A CD-ROM Drive. i) A PC compatible mouse & keyboard. Pentium and Pentium Pro are registered trademarks of Intel Corporation.
1.4 Specifications ENVIRONMENTAL Operating Temperature: 0 °C to +50 °C Storage Temperature: -55 °C to +75 °C Humidity: 95% non-condensing POWER REQUIREMENTS PCI bus loading: +5 Vdc @ 350 mA., +3.3Vdc @ 50mA. +12 Vdc @ 140 mA.* (w/o camera) -12 Vdc @ 110 mA.
1.5 Safety Considerations While the LBA-PC does not present the operator with any safety hazards, this instrument however is intended for use with laser systems. Therefore, the operator should be protected from any hazards that the laser system may present.
Chapter 2 EQUIPMENT SETUP 2.1 Equipment Setup This chapter describes how to get started using your LBA-PC. Follow these steps: Step 1) Install your LBA-PC fr ame grabber card into your PC. Step 2) Hook up your camera. Step 3) Turn on the system and setup your windows environment.
Note: If you purchased the optional 4 camera adapter, or the optional digital adapter then make sure that the slot immediately to the le ft (viewed from the front of your PC ) of the above PCI slot is also empty, and remove its rear filler bracket also.
The optional adapters use the rear panel openi ng, but do not pl ug into any of the PC expansion slots. Rather it i s provided with a short ribbon cable t hat plugs into the frame grabber card. (See figures below) Sl ide the adapter into the rear opening and plug its cable into the frame gr abber card.
Digital Camera Option Figure 4 Replace the cover of your computer. Restore the AC power to your computer. Note: The location of t he connectors may vary depending upon which frame grabber model is being install ed. The older LBA-400/500 series has a sli ghtly different arrangement but the concept remains the same.
2.1.2.1 An alog Cameras Connect the video out from your camera to th e BNC connector on the LBA-PC frame grabber card. This is the camera 1 input channel. If you have the 4-camera adapter option, then camera 2’s input is at the top, 3 in the middle, and 4 at the bottom of the adapter bracket assembly.
Step 7) Double click the file in the LBA-PC folder named “Setup.exe” to launch the install. (The windows file extensions, for this folder, mu st be set to viewable to see the “exe” extension.) Step 8) Follow the instructions in the installation dialogs.
2.1.5 Step 5 Configure Camera Type You should now have the LBA-PC application window on your monitor. The default configuration is for a basic CW laser setup.
The factory-supplied configuration files are write prot ected, so that you cannot accidentally lose or overwrite them. Each of these file names begin wi th a ~ (tilde), for easy identification. Some examples of these files are: ~lbapc.cfg The original default configuration.
• Click on the Sound, video and game controllers listing. • If the LBA-PC frame grabber was detected, and the device driver was not loaded you will see a category called Unknown in the edit box listing of the Device Manager. If this occurs, double click on the Unknown icon.
The device driver was unable to allocate enough memory in order to capture video frames. This may occur the first time you boot the computer after installing the Frame Grabber card. Try rebooting the computer. If the error continues to occur you w ill need to add memory to the computer.
2.4.1 Camera Power If your camera is a low power CCD style that runs on +12Vdc, then it may be powered from connector J1 (J3 on LBA-3/4/500 frame gra bbers) pin 6 (+12Vdc) and pin 5 (gnd). Caution: Do not atte mpt to power more than ONE camera from the LBA-PC.
2.4.3 Trigger Out Connector J2 (J5 on LBA-3/4/500 frame grabbers) pin 3 is the Trigger Out signal. This signal is factory set to output +5Vdc pulses. You can change this signal to +12Vdc level pulses by moving Jumper E1 (E4 on LBA-3/4/500 frame gr abbers) to bridge pins 2-3.
2.6 Special Setup for Pyrocam I Operation You must use special setups if you want to successf ully interface your Pyrocam I with a Model LBA-PC frame grabber system. It is strongly recommended that you first become familiar with the operating characteristics of both your Pyrocam I and LBA-PC before attempting to operate them together.
2.6.1.2 Setup requirements for LBA-PC with pyrocam cameras: Two files are provided for configuring the LBA to a Pyrocam I. They are ~PYROCAM.CFG and ~PYROCAM.CAM. 2.6.1.2.1 Setting up the Pyrocam Configuration. Go to File. . . Restore Config. . . and set the configuration to ~PYROCAM.
2.6.1.3.5 Camera settings restrictions Under no circumstances, make any changes to the Advanced. . . Camera settings for the Pyrocam I. 2.6.1.4 Image synchronization considerations The Pyrocam I’s CCIR video output is always produc ing video images at the rate of 25 frames per second.
2.6.2.1.1 Set video switch The Pyrocam must be set to output digital video. This is accomplished by setting the MONO/DIG/VGA switch to the LBA position. See Chapter 6 in your Pyrocam Operator’s Manual. 2.6.2.1.2 Connect cable Connect the Pyrocam’s digital output to the digital input connector of the LBA-500PC.
2.6.2.3 Image Synchronization Considerations The Pyrocam I’s Digital Output only produces an im age each time new data is available. It will not continuously output the same frame repeatedly. Thus, the rate of new output beam images is a function of the Pulse or Chopping rate an d image processing time.
Chapter 3 MENUS AND DIALOG BOXES 3.1 File. . . Drop Down Menu Selections 3.1.1 File | Load. . . A saved data file can be loaded into the frame buffer for display and results processing. Four types of data file formats are supported and are delineated by their file extension labels.
Beginning with release v2.50, any of the three .lb3, .lb4, and .lb5 file types can be read by any of the LBA-300/400/500PC model types. However, the new .lb4 and .lb5 file types cannot be read by software released prior to v2.5. Beginning with release v4.
If the file that you are loading contains multiple records, enter the starting number of the record that you want to begin loading from, in the edit box labeled Start Record . Enter the Number of Records that you want to Load. You can enter a value of 0, or 1 to the number of records in the file.
3.1.2. 1 Save As … Dialog Box Enter the drive:paths<filename> of the File that you want to save. Press Browse... if you want to append or overwrite an existing file, and you are not sure of the file’s name or location and wish to search for it.
entries. The Summed image is organized Horizontal data first, left to right, followed by a carriage return, and then the Vertical data, top to bottom. Note: Exported image files cannot be read ba ck into the LBA-PC’s frame buffer. Use Save As... and Load.
<filename>000000.cma;<filena me>000001.cma;...<filename>NNNNNN.cma Click on the image file Export Format (or Formats) that you want to generate. 3.1.4 Save Config… to a file The current setup configuration of the LBA-PC can be saved to a disk file.
3.1.7 Generate Gain Clicking this item will cause the LBA-PC to execute an automatic Gain Correction calculation cycle. The results of this operation will store a gain correct ion table that will be used to preprocess all data frames newly acquired from the Frame Grabber card.
• The Hardware Zoom. • The Hardware Pan location. • The Camera Type or Resolution setting. • The Camera Electronic Shutter setting. • The Video Gain and/or Black Level settings. Warning: Gain Correction should be used w ith only one camera at a time .
Results Logging files will have a .rlg file extensio n name. Results Logging files are for exporting numerical results to other applications, such as Spre adsheets or Math programs. Text editors can also view them. Results files are saved in ACSII. Export Logging files can be of four different file type s, .
If you choose Results Logging , select the Format that you want the data to be logged in. Both formats will produce an ASCII text log with comma-delimited entries.
If you use the Frames or Time method, the logging operation will automatically Stop! when the Frame count or the Timer values have run out. To protect the log file from inadvertent additions, use the above described terminate method to secure your log file.
Because of the flexibility in setting control options, it is possible to set conflicting control parameters. Therefore, it is essential that these various con flicts be resolved by a prioritized control scheme. Of course, a perceptive operator can avoid all of these possible conflicts.
If Results Logging and Statistics are both in play, and if the Statistics feature is in control: The Statistics results are recorded into the Result s Log file when the Statistics collection cycle is completed. 3.1.13 File | Print… The Print dialog box is where you tell the LBA-PC what information you want it to print.
specifying the From Start Frame location, and the Number of Frames to print. The Number of Frames can be 0, or 1 to the number of frames in th e frame buffer. 0 means all the frames in the frame buffer. When printing multiple frames you will observe that the LBA will cycle through the designated frame locations.
3.1.16.1 Save FROG as…Dialog Box Enter the drive:pathsand <filename> of the FROG File that you want to save. Press Browse… if you want to overwrite an existing file, and you are not sure of the file’s name or location and wish to search for it.
3.1.16.2 FROG Data Orientation The FROG software has the ability to flip axial a ssignments and directions. There is, however, a legacy defined orientation that we use as a basis for defining our axial representations. This is also the FROG default condition.
• DO consider Frame Summing if the FROG pulses are too weak to yield sufficient amplitude. • DON’T use the pan and zoom features or you will mess up the scaling parameters. You can minimize the Pan/Zoom child window to reduce temptation. • DO consider Frame Averaging if the FROG pulses are noisy.
3.2 Options... Drop Down Menu Selections 3.2.1 Hide/Show; Capture, Display, Aperture Toolbar The above three toolbars can be selectively displa yed or hidden based upon operator preference. Check the action that applies. The Capture and Display toolbars can be user defined to match the operators needs.
3.2.2.2 How to create a Drawn Aperture You can create a Drawn aperture by using the Aperture dialog box, the Aperture toolbar, or by dragging and dropping the aperture in the 2D display window. Note: Before you can use the drag and drop method you must first select a Drawn aperture shape using either of the first two methods.
Move the arrow cursor over the display window and press and hold down the RIGHT mouse button. This will reveal the Drag, Drop and Rotate hot spots of the Drawn aperture. Move the arrow cursor onto one of these hot spots, release the RIGHT mouse button and press and hold down the LEFT button.
3.2.3 Camera... selection and display resolution The Camera dialog box is where you make the following selections: • Identify current Camera type, or Create a New Camera type. • Select the maximum image Resolution. • Select how large the Frame Buffer will be.
• Type in the new camera pixel scale value. • Verify that the Pixel Units are set correctly, change as required. • Double-click inside the Camera type edit text control. • Type in a new 8 character file name. The .cam extension will automatically be added if you fail to include it.
The Full 1x resolution will create an image size equal to the Horizontal Size and Vertical Size shown in the Camera…, Advanced dialog box. This size is the maximum obtainable from the type of analog camera selected. Digital cameras do not follow the above resolution table.
to use virtual memory as Frame Buffer space. A little virtual memory assigned to the frame buffer is not too bad. A lot can make you wo nder what kind of alien being has just taken over your hard drive. Also, Windows will allocate real memory first, and when it’s gone, begin allocating virtual memory.
3.2.3.7 Pixel Scale, Pixel Units For analog cameras that use the Genlock sync source, only the V ..ertical Pixel Scale is set. The pixel scale value is derived from your ca mera’s detector specifications, or is user programmable to match the characteristics of your optical system.
3.2. 3.9 Lens Click on this box if your camera is fitted with a lens. When enabled the 2D image orientation is adjusted to depict the image as if the observer is standing and viewing the scene from behind the camera. When disabled, the 2D image is oriented as if the observer is standing in front of the camera looking at the surface of the detector.
Figure 17 The user can assign certain of these capture control items to the Capture Toolbar . The assigned items will appear on the toolbar in essentially the same order that they are listed in this dialog box. The operation of each item from the Toolbar is identi cal to their operation from this dialog box.
frame, and then Stop! . Successive clicks on Start! will each cause one additional frame to be acquired. The Interval setting has no effect. • Block: This method will cause a Block Length specified number of video frames to be acquired from the frame grabber.
file record number, and the Number of frames or records to post process. The number of frames can be 0, or 1 to the number of frames in the frame buffer or file. 0 means all the frames. The resulting frames will be placed sequentially into the frame buffer, beginning at the current frame buffer location.
Figure 19 Operating hints: • Increasing Video Gain also increases video noise. Use Video Gain sparingly, or not at all. Leave it set to 1 whenever possible. • The Black Level will be adjusted automatica lly each time you perform an Ultracal! calibration cycle.
3.2.4.3.3 Automatic Camera Switchin g Using the Four Camera Option With the four-camera option automatic switchin g between camera inputs is made possible by checking more than one camera enable at a time.
• Trigger Out: If your laser is a pulsed type, an d you would like the LBA-PC to provide an output pulse that will cause the laser to be fired, use this setting.
See Chapter 5 for additional information and examples regarding Triggering. 3.2.4. 5 Processing The Processing panel is where you select how to proc ess digitized frames of data. This processing determines how each frame that is st ored in the frame buffer will be constructed.
• Ultracal processing cannot be a part of a post processing operation. Gamma Correction is also a type of processing. Gamma Correction is controlled from the Camera dialog box, as it relates to a specific camera’s characteristics. Gamma correction can be part of a post processing operation.
Note: This edit control is repea ted in the Beam Display dialog box and is available i n the Display Toolbar. • If the Set Reference Source item is set to Current Frame , the data in the currently viewed frame will be copied to the Reference frame. • If the Set Reference Source is set to Last Gauss , and the Gauss Fit item in the Computations.
3.2. 5.1 Loggin g This switch will launch you into the Data & Results Logging dialog box. 3.2.5. 2 Print This switch will cause the selected print options to be printed on your configured printer.
Figure 23 If you enter an Energy of Beam value of 0 (zero) the energy related results items, such as, Total ( energy ), Peak (fluence), Min , Gauss Height , etc., will be computed in processed digitizer units. Processed digitizer units are calle d counts, and are dimensionless.
For a detailed discussion of the above items s ee Chapter 4, Results Display, and Chapter 6, Computations. 3.2. 6.4 Beam Widt h Method The Beam Width Method edit selection will determine the technique used to compute the beam width results. The first two methods ( 4 Sigma and 90/10 Knife Edge ) are computed based upon industry standard definitions.
3.2.6.4.2 90/10 Knife Edge This Knife Edge method uses a fixed 90% and 10% of energy as the moving edge Clip% points. The correction Multiplier is fixed at 1.561. These settings will yield highly accurate second moment equivalent beam widths for beams that are predominantly TEM 00 in mode content, and for many other mixed mode comb inations.
3.2.6.5 Elliptical Check on the Elliptical box to cause elliptical calculatio ns to be performed. Having Elliptical results enabled will cause the nature of other ca lculations to be modified.
Hints: Use Drawn apertures and avoid Auto apertures when maki ng Top Hat measurements. Use Percent of Peak as your beam width method. Typical Percent of Peak Clip% settings are 50% , 80%, and 90%. Refer to the Top Hat section in Chapter 6 for additional details.
3.2.6.8.2 Far-Field Divergence Measurements The Far-Field method requires you to measure the beam widths of your laser at two known locations in the beams far-field. The change in size is used to compute the rate of beam divergence in mili-radians. First collect a pair of Reference beam widths.
Figure 28 Enter the Bucket Size in the provided edit control. A good value to start with is 16, 64, 256 or 1024, depending upon which model frame grabber yo u are using; an 8, 10, 16, or 14 bit format respectively. Refer to the Histogram section in Chapter 6 for additional details.
from the point of interruption. Rather the cycle resets to the duration values set in the dialog box, but does not clear the prior accumulated stats. If you click on Start! after the frame count or timer has run out, the collection process will continue to add more data to the result s until the cycle completes a second time.
3.2. 7.1 Beam View Inside the Beam Display… dialog, click either the 2D or 3D radio button for the display mode that you want to view your beam in. You may also toggle beam display with the 2D/3D button on the toolbar.
Note: You must have the Elliptical computations turned on to permit the Major/Minor orientations to operate correctly, otherwise it will revert to the X/Y operating mode. 3.2.7. 4 Origin Locati on The beam display window will always have an X/Y origin from which all other positional data will be referenced.
3.2.7. 5 Beam Colors Your choice of beam display colors depends upon which display mode you have selected. There are 3 choices available in both 2D and 3D modes, plus 2 additional choices in 3D mode. They are: • Color Bands : 16 colors plus white to indicate intensities at, or near, A/D converter saturation.
Another Hint: A good time to use Z Axis Scaling is when you need to view the low energy dow n in the wings of your laser beam. Kick the scaling up t o x8 , leave the scale scroll bar at the bottom of the sli der, and maybe add in a little video gain and some frame averaging to quiet t h e noise.
appear in the display. This profile is a proj ection of the Current beam plus the Reference beam. All projections are made from the Cursor positions. 3D The Current beam will be displayed in Red . The Current plus the Reference will be displayed in Blue .
• If the Set Reference Source is set to Auto Gauss , and the Gauss Fit item in the Computations dialog box is checked, then the beam profile resulting from a computed Gaussian fit to newly acquired frames will be automatically copied to the Reference frame.
3.2.7.11 Copy Image to Clipboard If you click on the above button, the currently displayed frame image will be copied to the Clipboard in a .bmp format. This is a handy method for quickly exporting images from the LBA- PC application to another application without having to go through the Export Image process.
• Peak : Crosshair will be displayed, and its locati on is automatically drawn at the peak energy location of the beam. Note: This operation will not function correctly if the results window is minimized. • Origin : The Crosshair will locate to the position of the Origin .
the color style selected to a Light Gray. Only the Contour display will remain in the selected Beam Color . Hint: Use the Color Continuous Beam Color type when using the Contour di splay style. 3.2.7.14.3 Rotate and Tilt You can use these edit controls to set the Rotate and Tilt angles of the X, Y, and Z axes.
Figure 33 Note: Whenever you do a Soft Zoom while in 3D mode, th e Wire Density will go to the highest resolution value possible, based upon the camera resolution setting.
Figure 34 Note: The LBA-PC program must be running, collecti ng data and non-minimized for th e pointing stability program to collect data. 3.2.9. 1 Main Controls The main controls are located in a toolbar in th e upper left corner of the main window.
3.2.9.1.1 Start Button The Start Button begins data collection. However, if the LBA-PC is not collecting data in the background, then clicking this button will not result in data being plotted. In order for Beam Stability to work, the user must make sure that LBA-PC is open and collecting data in the background! 3.
Figure 36 A sample of data is defined as; any results comp uted from a discrete beam image captured from LBA-PC. The beam stability window will compute it’s results based on samples taken from the time the Start arrow is clicked, until the beam display is Reset , or until the application is closed and restarted.
Example: If the user has collected samples [1-1000] and the Sample limit it set to 100, samples [900-1000] will be the only samples visible in the strip chart. Statistical results will be computed using all the samples [1-1000]. 3.2.9.2.2 Samples The Samples indicator shows the total number of samples collected.
to use it as it relates to pixel units on the dete ctor array. If you choose to do pointing stability using spatial units such as mm or µm; the bins of the scatter/histogram plot and the horizontal and vertical grid lines will not have any correlation to the individual pixels on the detector.
Figure 37 The Centroid and Peak Histogram windows now have horizontal and vertical plot scaling in units of pixel, with histogram bins the size of a single pixel.
Figure 38 3.2.9.3.1 Zooming Histogram Plots The zooming feature for histogram plots works basically the same as it does for the strip chart window. (See Strip Chart Zooming) 3.
Figure 39 Note how peak locations seem to fall in a grid like pattern. This is to be expected when you are capturing every 4 th pixel. 3.2.9.3.3 Real World Units Setting LBA-PC’s Quantitative result.
3.2.9.3.4 Increment Bins and Reset The centroid scatter-plot is also a histogram of the centroid location. The color bar between the Peak and Centroid plots provides the user insight about centroid location/frequency. Colors in the upper part of the ba r indicate higher frequencies.
Figure 40 Upon opening, the above two horizontal color bars will be black. The designer can create a new palette by placing seed colors into the upper bar an d observing the resulting palette in the lower bar. Colors on the left represent low intensities while co lors on the right represent high intensities.
Figure 41 The user can either select one of the basic colors fr om the set on the left of the dialog, or create a custom color using the controls on the right. Clic king OK will place the selected color into the upper bar. Continue to add seed colors until the disp layed palette matches your desired effect.
Note: Palettes saved as .pal file types cannot be loaded into the Pale tte Generation Tool (PaletteGen2.exe) for editing! 3.2.10.3 Load Colors The Load Colors button is used to load the seed colors from .sp2 files into the Palette Generation Tool for editing.
3.2.11 Password Lockout You can enter a Password that will cause all of the LBA-PC setup functions to become inaccessible. The password acts as a toggle. Type in the password once and all setup options will become disabled. Type it in a second time and setup capability will be restored.
3.3. 1.1 PASS or FAIL results The remaining Pass/Fail dialog boxes are used to set the Pass/Fail limits for the results items that you want to test and screen for. When you check an item, you turn on the Pass/Fail screening for that particular result.
3.3.2. 2 Centroid The Centroid Pass/Fail item allows you to define a circle that must contain the centroid of the beam energy. To implement this test you must define the location of the center of a circle in terms of its X and Y coordinate in the beam display window, and the Radius of the circle that must contain it.
3.3.5. 1 Top Hat F luence The Top Hat computational results displays a value for the Max and Min fluence observed in a Top Hat beam’s energy profile. This result is affected by which Top Hat method is being employed. The Top Hat Fluence Pass/Fail edit control items are applied to both the Max and Min fluence results.
3.4.1 Tile Click on the Tile item to force all of the LBA-PC child Windows to return to their default sizes and locations. 3.5 Start!/Stop!... A Toggle Menu Action Item Activating the Start! menu item will cause the LBA-PC to start collecting and processing frames of data.
3.6.2 What Disables Ultracal! Ultracal will become DISABLED if certain data colle ction conditions, that were in effect when the Ultracal operation was executed, are no longer in effe ct. In all cases, these conditions are the result of an operators change to the spatial acquisition settings.
Notice: Some cameras suffer a reduced operati ng dynamic range when very short exposure times are employed. This can be seen as a dramatic change in the camera base line or as a reduction in the ca mera’s saturation level. If your camera reacts in one of these ways you may find t hat the AutoExposure technique will fail to yield optimum results.

Chapter 4 DISPLAY WINDOWS 4.1 Main Window You will probably want to run the LBA-PC application main window in its maximized display size. This will allow you to cram as much information as possi ble onto your display. We recommend that you operate in a minimum 1024x768 mode, larger if your graphics hardware and monitor will support it.
Figure 45 4.2.1 Frame Comment The Frame Comment is a text string label that you can attach to a data frame. It can be saved with the data file, and it will print as a title if you choos e to print the associated frame. You can replace the <Frame> number by double-clicking inside the Di splay Window’s title bar.
<Frame> number will appear. Both the comment and the data frame can, however, be Write Protected. If the Assign to All frames box is checked: This comment will be applied to all valid frames in the frame buffer. • Empty frames will not be commented.
4.2.2 Shortcuts In the Beam Window… Double left click to bring up the Beam Display dialog box. 4.3 The Results Display Window This window will display the computed results based upon the selections enabled in the Computations dialog box. You can minimize, maximize, or resize th is window.
Figure 49 Hint: A short cut that will turn off the co mputed results is to minimize this window. 4.3.1 Shortcuts In the Results Display Window… Double left click to bring up the Computations dialog box. Right click to bring up a Shorthand Results selection pop-up window.
4.4 The Pan/Zoom Display Window This window provides you with a graphical represen tation of where and how the digitized image relates to the detector on your camera, and the tools to modify those setting. The regions indicated in this display are not drawn to scale.
4.4.1.1 Analog Camera Zooming The chart below depicts the zooming process for an analog (non-digital) style camera. The starting point is based upon how you configured the image size and resolution in the Camera dialog box. First find your resolution factor in the top row.
4.4.1.2 Digital Ca mera Zooming Digital camera zoom image sizing does not follo w the same powers-of-two rule that is shown above for analog cameras. For digital cameras both the Full 1x and the 1x resolutions are the same size, and that size is set to the maximu m imager dimensions that the Spiricon frame grabber can reliably capture.
Figure 53 4.4.4 Zooming and Panning Constraints The Camera Resolution that you have set in the Camera dialog box will constrain how your displayed image can be positioned by the Panning and Zooming controls.
4.6 The Histogram Display Window This Histogram display window is visible only when the Histogram check box is enabled in the Computations dialog box. This wind ow can be minimized and resized. This bar chart is a fluence Histogram of the currently displayed frame of data.
4.7 Shortcuts using the Mouse A number of shortcuts are available that allow you to access some of the dialog boxes without going through the menu drop downs. These involve placing you mouse cursor into a region of a child window and then clicking either the right or left mouse button.

Chapter 5 TRIGGERING TYPES & CAPTURING METHODS 5.1 Triggering the LBA-PC The LBA-PC can support four basic types of triggering: • CW (or no trigger required), for lasers whose light output is continuous or pulsed at such a rate as to appear continuous to a camera (typically faster than 1000 Hz).
Since the perfect camera has not yet been found, we advise most LBA-PC users to operate pulsed lasers in Trigger Out mode whenever possible. Next best choice is the Video Trigger mode. These two modes will produce the most repeatable quantitative results.
field rate of 60 Hz can cause a trigger pulse to ou tput at a 30 Hz rate. A non-interlaced camera running at a frame rate of 60 Hz can produce a trigger output pulse at a 60 Hz rate. 5.1.3.2 Trigger Delay The LBA-PC will produce trigger output pulses at the programmed frame Interval rate.

and ½ the maximum possible counts based on the number of A to D conversion bits. For example: If you are using an LBA-712PC frame grabber (a 12 bi t digitizer) you have the following possible Video Trigger Level choices: 256, 512, 1024, 2048.
Example: With the Capture Interval set to 10, and a 30 Hz frame rate camera, the capture rate will be 3 fps. 5.2.1.2 With Trigger Type set to Trigger Out The frame rate of the camera and the Trigger and Capture Intervals will combine to determine the capture rate.

Chapter 6 COMPUTATIONS 6.1 Computational Accuracy Once you have mastered the skill of acquiring your laser beam's profile on the screen of the LBA-PC, your next thoughts will usually be directed toward the accuracy of the quantitative results. The degree of accuracy of the computed results will be based primarily upon two factors.
6.3 Beam Presentation Affects Results Effective beam presentation is essentially an attemp t to improve accuracy by increasing the signal-to- noise property of the digitized data. Since the came ra and the digitizing process primarily fix the noise level, most of our efforts will concentrate on increasing the signal content.
Ultracal! every 10 to 15 minutes, or whenever you th ink your camera may have strayed. This drift can be observed as changes in the background nois e image. Un-illuminated areas will appear as gray and dark violet (almost black) rand om noise. If the background starts to look too gray then the baseline is drifting negative.

Chapter 10 REMOTE GPIB OPERATION 10.1 Introduction The LBA-PC can be controlled as a remote devic e via GPIB. For the most part, communications between the LBA-PC and the host controller will follow the data format and coding protocols outlined in the IEEE 488.
5. Click on the Advanced tab, make sure that Automatic Serial Polling is not checked. 6. Click OK. NOTE: It is possible for the LBA-PC t o generate many service requests per second and the NI-488.2M def ault is to queue service requests. For these reasons we suggest you disable Automatic Serial Polling on both the LBA-PC and the host controller.

10.8 ERROR MESSAGES Since the LBA-PC is pretty much of a black box and the GPIB is not much better we have included descriptive error messages and other information to make debugging a little easier. The LBA-PC maintains two output queues, the respon se output queue and the error message queue.
The second category of errors is LBA-PC exec ution errors. These error messages are normally displayed in a message box on the screen. The LBA-PC reroutes these error messages to the error message queue when the queue is enabled.

B.3.1 Basic Results .vi This program shows the basic communication between LBA-PC and the local computer. It contains three buttons: “Run/Stop”, “Ultracal”, an d “Auto Aper on/off” on the left side of the window. This VI shows all basic results on the right side.
• Get Basic Results .vi These VIs are easy to understand if one has so me experience in LabVIEW programming. The processing sequence is controlled by the “Error In” and “Error Out” connection chain. That means a function unit is processed earlier if it is closer to the starting “Error In” connection.
3. Check if the status of the cursor display has changed. 4. Check if any Cursor-Move button has been clicked. 5. Check if the ZoomIn and ZoomOut button has been clicked. Check if any Pan- Move button has been clicked. 6. Get current frame data and cursor location to display.
B.3.9 Get Data .vi This VI will download a data frame from the LBA- PC into a file on one of the local computer’s hard drives. The operator must enter the file name and path, and the Frame Number that is to be transferred.
