Timing control of light beam scan |
摘要 |
A circuit for controlling scanning of light includes a detection-signal processing unit which generates a detection signal indicative of a timing at which a light beam hits a predetermined reference position, and a clock-generation unit which generates a clock signal in synchronism with the detection signal such that a timing of the clock signal is adjustable by the detection signal independently of a length of one clock cycle of the clock signal, wherein the clock signal synchronizes the light beam.
