Distance measurement apparatus and method

摘要

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.

1. A distance measurement apparatus, the apparatus comprising:
a light source to output light; a switch array including a plurality of cells, and to control a position at which the light output from the light source is irradiated, by switching operations of respective cells of the plurality of cells of the switch array; a light detector including only a single cell, and to sense the light reflected from a target object; and a controller that sequentially controls the switching operations of the plurality of cells of the switch array, the controller to generate distance information corresponding to a distance between the light source and the target object, based on the light sensed by the light detector.
