Abstract
A laser radar including laser beam generating means, photo detecting means, a mirror, 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 includes a through-hole that passes 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 deflects the laser beam toward a measuring region and reflects the reflected laser beam from the object toward the mirror. The rotation driving means rotates the light deflecting means so as to direct the laser beam toward the measuring region.
