Abstract

See full text

A light source device including a light emitting unit in which multiple light emitting elements including vertical cavity surface emitting lasers are arranged is intended to curb temperature rise. A light source device according to the present technology includes a light emitting unit in which multiple light emitting elements including vertical cavity surface emitting lasers are arranged, and a driving unit that, regarding the light emitting element in the light emitting unit, causes multiple light emitting elements to be caused to emit light in a light emission target period to emit light in a time-divided manner in the light emission target period. By adopting time-division light emission, the number of light emitting elements that are caused to emit light simultaneously is reduced.
