Patent ID: 8345339

Claim:
An optical deflector comprising: a deflector including a vibrational system having a movably supported body with a light deflecting member, the deflector deflecting light from a light source; a vibration detector configured to detect tilt angles of the movably supported body of the vibrational system of the deflector throughout reciprocating movement of the movably supported body; a driving signal generator configured to generate a driving signal for driving the vibrational system of the deflector; a modulation timing signal generator configured to generate a modulation timing signal for regulating timing for modulating the amount of light from the light source; and a deflection detector configured to detect a deflection condition of light from the light source deflected with the deflector, wherein the driving signal generator generates the driving signal based on information of the tilt angles detected by the vibration detector, and wherein the modulation timing signal generator generates the modulation timing signal based on information of the deflection condition detected by the deflection detector.
