ABSTRACT:
An object detecting apparatus having a laser radar with a single light sensing element for foreign matter detection is disposed behind a front grille of a vehicle. The apparatus includes a projection window. The apparatus uses a laser beam for object detection. The laser beam includes a main portion, an upper scattered portion, and a lower scattered portion. The single light sensing element is so positioned that it collects reflection of the lower scattered portion of the laser beam reflected on the projection window and reflection of the upper scattered portion of the laser beam reflected on the front grille.
