Abstract

PURPOSE:To detect distance information and the brightness of reflected light by combining a 1st light receiving body having a light receiving surface in the band shape of uniform width and a 2nd light receiving body having a light receiving surface in a pointed strip shape so that the respective light receiving surfaces are alternately arranged to form a blind shape. CONSTITUTION:A range finding photodetector 10 equips the 1st light receiving body 11 and the 2nd light receiving body 12 which are electrically independent from each other. The 1st light receiving body 11 has a base part 13 and plural light receiving surfaces 14 arrayed in interdigital shape and the 2nd light receiving body 12 has a base part 15 and plural light receiving surfaces 16 arrayed in interdigital shape. And the 1st light receiving body 11 and the 2nd light receiving body 12 are combined in the blind shape where the light receiving surfaces 14 and the light receiving surfaces 16 are alternately arranged. The 1st light receiving body 11 receives a light received image on its light receiving surface 14 of uniform width and gives an output according to the brightness of the reflected light and the 2nd light receiving body 12 receives the light received image on its light receiving surface 16 of the pointed shape and gives the output of displacement information of the light received image. Thus, the detection of the distance information and the detection of the brightness of the reflected light can be executed with a single photodetector.
