Abstract

A distance measuring apparatus includes a light source to emit light beams, an optical scanner to scan the light beams output from the light source over a predetermined range, a light receiver to receive reflected light obtained as a result of the light beams being reflected by a target object, and to output detection signals, and a control circuit to measure a distance to the target object based on the detection signals. The light source including a plurality of light-emitting device groups that are arranged in a scan direction of a scan performed by the optical scanner, and the control circuit being to make the plurality of light-emitting device groups emit light at respective different timings in a single scan, and to measure the distance to the target object based on a sum of the detection signals.
