Abstract
A light deflecting device is a light deflecting device for deflecting an incident light beam and has: a coarse motion light deflecting device which has an optical system having at least two conjugate points on an optical axis and deflects the light beam which has passed through one conjugate point and has entered the optical system as an output light beam which passes through the other conjugate point and has a deflection angle with respect to the optical axis while changing its transmitting direction; and a fine motion light deflecting device which is arranged in the optical system, applies a deflection to the incident light beam, and changes the deflection angle of the output light beam to a second deflection angle different from the deflection angle for a predetermined time.
