Abstract
An optical deflector which deflects incident light, includes an optical deflection element which deflects the incident light when a distribution of internal refraction indexes of the optical deflection element is modulated. The light incident on the optical deflection element is emitted from the optical deflection element after passing through the optical deflection element a plurality of times.
