Adjust the Strobe Delay (in milliseconds) to determine the interval between the
moment when the exposure begins and the moment when the strobe output
pulse initiates.
Pixel Scale and Units
Enter a vertical and horizontal Pixel Scale value appropriate for your optical
system and camera.
The pixel scale value is derived from the camera’s detector specifications, or may
be user programmable to correspond to 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.
Select the Pixel Units value that applies to the entered pixel scale value.
Camera detector pixel pitch is specified in micrometers (µm).
Gamma Correction
If the camera employs a solid state CCD or MOS style detector, then its detector
responds linearly to monochromatic light. For linearly responding cameras the
Gamma setting should be set to 1.
Lens
Check this box if the 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.
