Abstract

There are provided a distance measurement apparatus and a distance measurement method, the distance measurement apparatus including: a light source outputting light; a switch array including a plurality of cells, and controlling a position at which the light output from the light source is irradiated, by switching operations of the respective cells; a light detector sensing the light reflected from a target object; and a controller sequentially controlling the switching operations of the plurality of cells of the switch array, wherein the controller generates distance information between the light source and the target object based on the light sensed by the light detector. The light detector including a single cell light detector element may be used, to thereby reduce the costs.
