Abstract
An optical deflection apparatus is provided with an optical deflection element and a compensating optical element. The optical deflection element deflects incident light in a first direction (a voltage application direction) in which a voltage is applied (one-dimensional scan). The compensating optical element is an element which has an incidence surface and an emission surface, which compensates for a deflection deviation in a second direction that is perpendicular to the first direction and to an optical axis of the incident light of deflected light having been deflected by the optical deflection element and incident from the incidence surface, and which arranges a direction of travel of compensated light to be emitted from the emission surface on a same plane.
