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 28 µm x 14 µm pixel (1k and 2k
models), or a 20 µm x 10 µm pixel (4k model).
The sensitivity mode is software-controlled through the set sensitivity command: ssm.
Figure 18: High Sensitivity Mode
In high sensitivity mode, the camera uses either a 14 µm x 14 µm pixel (1k and 2k models) or a 10 µm x 10
µm pixel (4k model) and captures the same image twice, resulting in a brighter image.
Figure 19: Low Sensitivity Mode
In low sensitivity mode, the camera uses either a 14 µm x 14 µm pixel (1k and 2k models) or a 10 µm x 10
µm pixel (4k model) and captures the image using one sensor (Sensor 1).
Figure 20: Tall Pixel Mode
In tall pixel mode, the camera uses a 28 µm x 14 µm pixel (1k and 2k) or a 20 µm x 10 µm pixel (4k model)
and captures an image two times taller than in high or low sensitivity modes, resulting in a taller image.
