Sigma LBA-708, LBA-710, LBA-714PC, LBA-300 manual Setup requirements for LBA-PC with pyrocam cameras

2.6.1.2Setup 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.

2.6.1.2.1Setting up the Pyrocam Configuration.

Go to File. . . Restore Config. . . and set the configuration to ~PYROCAM.CFG.

2.6.1.2.2Setting the camera type to Pyrocam

Go to Options. . . Camera dialog box and set the Camera selection to ~PYROCAM.CAM. This may already have happened when you did the previous step.

The ~PYROCAM.CAM file is absolutely required for correct operation with your Pyrocam. The ~PYROCAM.CFG configuration is a good starting point configuration.

You will undoubtedly need to make changes to your configuration to suit your application. Do so, and then save off your new configurations into new <filename>.cfg config files. Remember the ~PYROCAM files are read only; so don’t try to use those file names.

2.6.1.3Some Restrictions apply when interfaced to a Pyrocam I

2.6.1.3.1Frame resolution restrictions

While you are not restricted from setting your frame Resolution to 512x480x1, it is not a good idea. Keep your Resolution setting set to 128x120x4. Remember the Pyrocam creates a 124x124 sized image, so setting higher resolutions only wastes memory and slows down operations.

2.6.1.3.2Zooming restrictions

In keeping with the above, do not use Hardware zooming. Only use Soft zooming, i.e. double-right-mouse click in the Zoom window.

2.6.1.3.3Restricted pixel regions

Because of the image size difference between the LBA and the Pyrocam I, as noted above, the LBA will clip off 4 rows from the Pyrocam; two on top, and two on the bottom. Also the LBA will have 4 dark columns; two on the left edge, and two along the right.

2.6.1.3.4Scale and resolution restrictions

Note also that the Pixel Scale setting is set to 25mm, not 100mm, which is the actual pixel scale of the Pyrocam I. This is because the image output by the Pyrocam in CCIR mode is 4 times over scanned in both the x and y directions. Thus the LBA’s 1x resolution comes out to be 1/4th the 4x resolution. Keep this in mind if you plan to change the scaling because of placing the beam altering optics in the beam path.
