ABSTRACT:
There is provided a laser radar apparatus including laser beam generating means, photo detecting means, a mirror assembly, light deflecting means, and rotation driving means. The laser beam generating means emits a laser beam having an axis thereof. The photo detecting means detects a reflected laser beam that is reflected back by an object. The mirror assembly includes a through-hole that transmits the laser beam and a reflecting surface that reflects a reflected laser beam reflected back by the object toward the photo detecting means. The light deflecting means has a flat mirror surface and a concave-shaped mirror surface, and reflects the laser beam toward a measurement range and deflects the reflected laser beam from the object toward the mirror assembly. The rotation driving means rotates the light deflecting means so as to direct the laser beam toward the measurement range.
