Abstract:
A distance measurement device includes a projection optical system, a light-receiving system to receive light projected from projection optical system and reflected by an object; and a correction system to correct a difference in timing of light emission between the plurality of light sources. The projection optical system includes a plurality of light sources and a plurality of drive circuits to drive the plurality of light sources.
