The LQ-401CL uses four high-performance CMOS line scan image sensors mounted on a prism
block.
During exposure, the incoming light is converted to electrons (electric charge) in the photodiodes
(active pixels). The transfer gate controls the transfer of charge from photodiodes to the shift
register. Activating the transfer gate terminates the exposure cycle, transfers the charge to the
Horizontal Shift Register (2-phase buried channel CMOS shift register) and starts a new exposure
cycle. The line is subsequently read out in a single sequence starting with pixel 1.
