Abstract
Disclosed is a laser radar device including a modulated light beam generator that emits light beams to a target, a photodetector that receives reflected light; a reflected light condenser that condenses the reflected light; a rotator that rotates around a rotation axis; and mirrors included in the rotator that scan the light beams, and guide the reflected light to the reflected light condenser, wherein an angular detection range in a vertical direction is divided into a plurality of layers, wherein mirror surfaces of the mirrors are tilted by corresponding tilt angles relative to the rotation axis, the tilt angles being different from each other, wherein the modulated light beam generator emits the light beams in the vertical direction, the light beams having different emission angles, and wherein a difference between the emission angles corresponds to the angular detection range of one layer in the vertical direction.
