Abstract
A distance measuring apparatus includes a projector configured to project laser beam at a projection angle to an object; a photodetector array in which a plurality of photodetectors are arranged; a condenser lens configured to concentrate, on the photodetector array, the laser beam reflected by the object positioned on a direction of the projection angle; a detector configured to detect an output of at least one of the photodetectors of the photodetector array; and a selector configured to select the photodetector from which the detector receives the output, depending on a distortion of an area on the photodetector array irradiated with the reflected laser beam when the projection angle is large, the area being determined by an angle of incidence of the reflected laser beam to the condenser lens, the angle of incidence being associated with the projection angle.
