ABSTRACT:
An optical radar apparatus, having a structure such that light generated by a laser generating means 1 is emitted to an object 100 while scanning the same, light reflected by the object 100 is reflected by a reflected-light reflecting means 10, and then a parabolic mirror or a concave mirror 19 receives reflected light above, is arranged to have a light receiving device 20 disposed at the position of the focal point of the parabolic mirror or the concave mirror 19 so as to obtain the distance to the object 100 and the direction of the same in accordance with propagation delay time taking from light emission by the light generating means 1 to receipt of reflected light by the light receiving device 20.
