Abstract

A beam deflection device includes multiple light-emission structures arranged adjacent to each other in a first direction (X direction). The light-emission structures are each configured to be capable of emitting, from its device surface, a line beam that extends in the first direction in the far field. Furthermore, the light-emission structures are each configured to allow the line beam to be scanned in a second direction (Y direction) that is orthogonal to the first direction.
