Abstract
An optical scanning device comprises a waveguide array, a first adjusting element, a plurality of phase shifters, a second adjusting element, and a control circuit. When light emitted from the waveguide array forms a light spot on a virtual plane that is spaced apart from the waveguide array, the control circuit causes the light spot to move in first and second directions such that the distance of movement of the light spot from start to finish of scanning of a target region is greater in first one of the first and second directions than in second one of the first and second directions.
