The camera uses DALSA’s dual line scan sensor. The camera can be configured to read
out in either high or low sensitivity mode, tall pixel mode, and forward or reverse shift
direction.

Sensitivity Mode and Pixel Readout
The camera has the option to operate in either high sensitivity or low sensitivity mode or
in tall pixel mode. When in high sensitivity mode, the camera uses both line scan sensors
and its responsivity increases accordingly. When in low sensitivity mode, the camera uses
the bottom sensor. When operating in tall pixel mode, the camera operates using both
sensors, creating a 28µm x 14µm pixel. The sensitivity mode is software controlled
through QuickCam or through the ASCII command ssm.
