You can change this signal to +12Vdc level pulses by moving Jumper E1 (E4 on LBA-3/4/500 frame grabbers) to bridge pins 2-3. Note: Jumper E1 (E4) controls the output signal level for both Trigger Out and Pass/Fail Out.
Page 27: Special Setup For Pyrocam I Operation
To operate your Pyrocam I with a model LBA-300PC or a LBA-400/500/708/710/712/714PC without a digital camera option, see section 2.12.1. To operate your Pyrocam I with model LBA-500PC-D or a model LBA-7XXPC-D, with the digital camera option, see section 2.12.2.
Page 28: Setup Requirements For Lba-Pc With Pyrocam Cameras
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.CFG. 2.6.1.2.2 Setting the camera type to Pyrocam Go to Options.
Page 29: Image Synchronization Considerations
Pyrocam were not equipped with digital outputs. If your Pyrocam I does not have a 50 pin connector on its rear cover it can not be interfaced as a digital camera. However, you can still interface it by using the analog method described in the LBA-300PC interface topic.
Page 30: Lba-500/7Xxpc-D Setup Requirements
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. A special interface cable is required to make this connection.
Page 31: Image Synchronization Considerations
2.6.2.3 Image Synchronization Considerations The Pyrocam I’s Digital Output only produces an image 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 and image processing time. For this reason, you should operate the LBA-500PC in Video Trigger mode only.

Warning: Gain Correction should be used with only one camera at a time. It will not correctly operate in conjunction with the for camera option when automatic camera cycling is enabled.
Page 40: Beginning And Terminating Logging
Results Logging files will have a .rlg file extension name. Results Logging files are for exporting numerical results to other applications, such as Spreadsheets or Math programs. Text editors can also view them. Results files are saved in ACSII. Export Logging files can be of four different file types, .bmp, .cma, .spa, .cur. Export Logging files are write only.
Page 41: Logging Method
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. The Spreadsheet format will precede the log with a single list of column headings. The Math Program format will precede each log entry with a binary number that indicates which results are enabled.
Page 42: Pass/Fail Filter
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. When Logging is Frames or Time limited, the Rate display will indicate the number of frames to or the time remaining .
Page 43: Combinations Using Logging, Statistics And Block Mode
Because of the flexibility in setting control options, it is possible to set conflicting control parameters. Therefore, it is essential that these various conflicts be resolved by a prioritized control scheme. Of course, a perceptive operator can avoid all of these possible conflicts. Nevertheless, owing to the complexity of these features, setup errors are almost a certainty.

Page 54: Frame Buffer Size
The Frame Buffer is loaded in a sequential round robin fashion. Frames of data can be placed into the frame buffer by: • Digitizing the video input signal. • Transferring data from a digital camera. • Loading in data from disk files. • Post processing data already in the frame buffer.
Page 55: Am I Using Virtual Memory Yet
Pixel Bits setting is –12. If your digital camera has more bits of resolution than can be accommodated by the LBA-PC, you must connect only the upper most significant bits. Any left over data bits will not be processed by the LBA-PC.
Page 56: Pixel Scale, Pixel Units
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 camera’s detector specifications, or is user programmable to match the characteristics of your optical system. For the camera imager based scale setting, the value to enter is the minimum line pitch of the camera’s detector.

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.
Page 58: Capture
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 identical to their operation from this dialog box. For simplicity, the following examples will refer only to the dialog box entries.

Page 68: Energy Calibration Procedure
If you enter an Energy of Beam value of 0 (zero) the energy Total ( ), Peak (fluence), Min, Gauss Height, etc., will be computed in processed digitizer units. Processed digitizer units are called counts, and are dimensionless. In this case, no units will be displayed in the results window.
Page 69: Beam Width 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. The remaining three choices are user definable, so use care in setting up and restoring their related options.
Page 70 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 content, and for many other mixed mode combinations.
Page 71: Elliptical
Hat results are computed. These choices and their affects are: • Data: This method will include all data above the Clip% level. If you are using 4 Sigma, or one of the Knife Edge beam width methods, the Clip% level is forced to 80% of peak. •...
Page 72: Divergence
Hints: Use Drawn apertures and avoid Auto apertures when making 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 Divergence Two methods are provided for making divergence measurements of your laser beam.
Page 73: Histogram
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.
Page 74: Statistics
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 you are using; an 8, 10, 16, or 14 bit format respectively. Refer to the Histogram section in Chapter 6 for additional details. 3.2.6.10 Statistics Check this box to enable the addition of Statistical information in the Results window.

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 results until the cycle completes a second time.
Page 76: Beam View
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: In general 3D displays will run slower than 2D owing to the amount of computations involved with generating the wire frame.
Page 77: Origin Location
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 Location The beam display window will always have an X/Y origin from which all other positional data will be referenced.
Page 78: Beam Colors
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.
Page 79: Beam Display
Another Hint: A good time to use Z Axis Scaling is when you need to view the low energy down in the wings of your laser beam. Kick the scaling up to x8, leave the scale scroll bar at the bottom of the slider, and maybe add in a little video gain and some frame averaging to quiet the noise.

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. In other words, the bins in the histogram and the pixel grid of the detector will not have the same crosshatch granularity.
Page 91 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. Note also that we have the same plot orientation as the LBA-PC beam window. In the Figure above we can see that most of the centroids are falling 232 pixels from the left and 247 pixels from the bottom (assuming that your origin is set to Window LL).

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). •...
Page 119: Trigger Type Cw
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. 5.1.2 Trigger Type CW The setup for CW timing is the least complex of the setups.
Page 120: Trigger Delay
field rate of 60 Hz can cause a trigger pulse to output 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.

5.1.3.7 CCD Frame and Interline Transfer Cameras, Non-interlaced (Progressive scan) These camera types can produce 1x high-resolution images. The video output from each laser pulse will occur during the next frame outputting immediately after the laser trigger arrives. 5.1.3.8 CMOS, CID Line Transfer and Tube Cameras, Non-Interlaced (Progressive scan) These camera types can produce 1x high-resolution images.

For example: If you are using an LBA-712PC frame grabber (a 12 bit digitizer) you have the following possible Video Trigger Level choices: 256, 512, 1024, 2048. If you set the level to 512, the LBA will capture a laser beam pulse as soon as it detects a pixel raw energy value of 512 or greater.

Page 128: Chapter 6 Computations
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. The first, and most significant, is the correct nulling of the background energy.
Page 129: Beam Presentation Affects Results
6.3 Beam Presentation Affects Results Effective beam presentation is essentially an attempt to improve accuracy by increasing the signal-to- noise property of the digitized data. Since the camera and the digitizing process primarily fix the noise level, most of our efforts will concentrate on increasing the signal content. Always try to optimize your beam's amplitude into the camera's dynamic operating range.

Effective Area. Depending upon the Beam Width Method, the clip level value is determined as follows: • With the 4-Sigma and Knife-Edge methods and with the Top Hat results disabled, the LBA energy totals the pixel values in descending order until it finds the pixel which causes the sum to exceed 86.5% of the total...

Clip% level. • If the 4 Sigma or one of the Knife Edge methods are chosen and the Top Hat calculations are not checked, the clip level is set to 86.5% of energy. If the Top Hat calculations are checked, then an 80% of Peak clip level is set.
Page 132: Beam Widths And Diameters
This definition has grown out of laser beam propagation theory and is called the Second Moment, or D-4-Sigma beam width. (The D erroneously stands for Diameter.) Sigma refers to the common notation for standard deviation. Thus an X-axis beam Width is defined as 4 times the standard deviation of the spatial distribution of the beam’s...
Page 133: Knife Edge Method
The standard deviations are derived from the variances of the energy distributions and are equal to the standard deviations squared. The variances are: Where: Z = the intensity of the pixel x and y are the coordinates of the centroid Only beam propagation factors based on beam widths and divergence angles derived from the second moments of the energy density distribution function, will allow one to predict how a beam will propagate.

This option will allow you to set up for beams requiring special settings, which could get you into all kinds of trouble, since you can set these values to just about anything you like.
Page 135: Gauss Fit
The Orientation of an Elliptical beam is determined from the clip level. A smaller percent of peak or larger percent of energy will include more pixels, in the orientation calculation. A larger percent of peak or smaller percent of energy will include fewer pixels. Depending upon your laser beam this setting can have serious implications.

A result of 0.8 tells us the data is a better Gaussian shape than a result of 0.7 and a worse Gaussian than 0.9, but it does not tell us how much more or less.

Page 177: Chapter 10 Remote Gpib Operation
Chapter 10 10.1 Introduction The LBA-PC can be controlled as a remote device 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 488.1 and 488.2 standards. This manual will not attempt to fully describe the nuances of the GPIB bus operation nor to convey fully the operation of the IEEE 488.1 and 488.2 protocols.
Page 178 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 to generate many service requests per second and the NI-488.2M default is to queue service requests. For these reasons we suggest you disable Automatic Serial Polling on both the LBA-PC and the host controller.

quantitative results, you will also have to retrieve that separately (see A.5.4.17 RDR?). If you wish to associate this information with a data frame, be sure to specify the same frame number for the data and status/results. Three commands allow you to download raw data or data at the cursors from any frame including the reference and gain frames.

Page 192: Frm - Upload Data Frame
LBA-PC sends FrameNumber=10; #532768(DAB)…(DAB) 10.6.2.2 FRM - Upload Data Frame To upload an LBA-PC data frame, you must send the FRM command with optional parameters that identify the frame number and whether to replace an existing configuration. The frame parameter is optional and is numbered from -1 to n. ‘n’ is the number of frames in the frame buffer.
Page 193: Ldd - Read Data File
FrameNumber=33; #6124928(DAB)…(DAB)(^END) The following example describes how the host uploads a data file to frame 25. The replace parameter is specified so the camera or camera resolution will be changed if the settings in the file are different than the current configuration. The pixel scale and energy calibration will also be changed to the file value if different than the current configuration.
Page 194: Sdd - Save Data File
• If the replace parameter is false and the pixel scale is different, then the pixel scale is not changed and the file is stored in the frame buffer. • If the replace parameter is true and the energy calibration of the file is different than the current configuration, then the energy calibration is set to the value in the file and the file is stored in the frame buffer.

Page 201: Pan/Zoom Window Detector Coordinates
Pan/Zoom Window Capture Window 10.7.2 Pan/Zoom Window Detector Coordinates Detector coordinates define locations on the camera detector. Detector coordinates are always positive integers. For a particular camera type, detector coordinates never change. The detector coordinate origin is always the upper left corner of the detector. This origin does not start at x=0, y=0, rather it relates to electronic timing of the camera.
Page 202: Dis - Set Manual Origin Location
Detector coordinates are used to position the origin location which in turn defines the World Coordinate system. Detector coordinates also are used to define the location of the frame data capture windwo which in turn defines the Frame Coordinate system. 10.7.2.1 DIS - Set Manual Origin Location The Origin location can be set anywhere inside the :PNW? limits.
Page 203 The PAN command is affected by the current capture resolution (zoom). Use the :PAN? command to retrieve the current capture window location and resolution. The capture resolution value is coded as a power of two. A capture resolution value of 0 represents 2 value of 1 represents 2 = 2, 2 represents 2 etc., the LBA-PC samples every pixel, every other pixel, every 4th pixel, etc.
Page 204: Frame Coordinates
The following describes how to set the pan window to the lower right corner of the detector. In this example the lower right corner of the detector is at (744, 512). The frame data size is 32 X 30. The capture resolution value is 2, so we must multiply the data size by 2 actual size of the capture window is 128 X 120.
Page 205: Beam Window World Coordinates
See section 2.3.1.1 RCC?, RCR? - Read Cursor Transfer for additional information. 10.7.4 Beam Window World Coordinates Most parameters that specify spatial coordinates must be in LBA-PC world coordinates. World coordinates are used for locations in the current frame as displayed in the beam window with no magnification.
Page 206: Error Messages
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 response output queue and the error message queue. To enable the error message queue, you must send the ERR command with a parameter specifying verbose error reporting.
Page 207 The second category of errors is LBA-PC execution 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. Example of a category 2 error: Host sends :PAN X=0;...

Cannot be set, information only. World coordinates are based on the frame size, capture resolution, origin location, and pixel scale. Use the WLD? command to determine frame current boundaries.
Page 265: Appendix B Labview Support
Appendix B B.1 Introduction LabVIEW is a product and registered trademark of National Instruments Corporation. LabVIEW is a general purpose programming system designed specifically for data acquisition and instrument control. LabVIEW programs are called Virtual Instruments (VI’s) because their appearance and operation can mimic other instruments such as the LBA-PC laser beam analyzer.
Page 266 SUBVI.LLB You can either copy these library files to your LabVIEW development computer, or read these files from the Spiricon supplied CD. B.2 The Basic SubVI Library Examples SUBVI.LLB contains 22 basic functions that can be called by other VI’s. The functions of these SubVI’s are analogous to subroutines in other types of programming environments, such as C++ .

Error in B.2.21 Semicolon String to Array .vi Description: Translate a string with semicolon delimiters to an array.
Page 272 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”, and “Auto Aper on/off” on the left side of the window. This VI shows all basic results on the right side. LabVIEW is a graphical computer language.
Page 273 • Get Basic Results .vi These VIs are easy to understand if one has some 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. In other words, we use the “Error Out”...
Page 274 Check if the status of the cursor display has changed. Check if any Cursor-Move button has been clicked. Check if the ZoomIn and ZoomOut button has been clicked. Check if any Pan- button has been clicked. Get current frame data and cursor location to display. B.3.3 Basic Divergence .vi This program is similar to the Basic Results .vi, but contains only those items needed to make...
Page 275 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.
