Sensitivity Mode and Pixel Readout
The camera has the option to operate in either high sensitivity (dual line) or low
sensitivity (single line) modes, 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 only. When operating in tall pixel mode, the camera operates using both
sensors, creating a 28µm x 14µm pixel (1k and 2k models), or a 20µm x 10µm pixel (4k
model).
The sensitivity mode is software-controlled through the ASCII command ssm.
Figure 3: High Sensitivity Mode
In high sensitivity mode, the camera uses either a 14µm x 14µm pixel (1k and 2k models)
or a 10µm x 10µm pixel (4k model) and captures the same image twice, resulting in a
brighter image.

Figure 4: Low Sensitivity Mode
In low sensitivity mode, the camera uses either a 14µm x 14µm pixel (1k and 2k models)
or a 10µm x 10µm pixel (4k model) and captures the image using one sensor (Sensor 1).
