Abstract
A photodetector measures flight time by an imaging optical element imaging reflected light from an illuminated illumination region of an object illuminated by pulse light, and a light detection portion receiving the imaged light. The light detection portion is formed larger than a projection region reflected at the illumination region of the object and imaged on the light detection portion. In the light detection portion, a portion overlaying the projection region is activated as a light-detection region.
