    Fig.9 Signals flow 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.
