<p>[Problem] To provide a laser radar capable of properly receiving reflected light from a target region even when the projecting optical system and the receiving optical system are inside the same chassis. [Solution] A laser radar (1) is provided with a laser light source (21), a mirror actuator (25) for driving a mirror (69), a light-receiving lens (32) for concentrating laser beam light reflected by the mirror (69), and a light detector (33) for receiving reflected light concentrated by the light-receiving lens (32). The laser light source (21) is positioned on the light path between the mirror (69) and the light-receiving lens (32). The mirror (69) is of a size such that light reflected therefrom passes around the laser light source (21) and is incident on the light-receiving lens (32). The light detector (33) is positioned behind the laser light source (21); hence, laser beams other than that reflected from the target region are unlikely to be incident on the light detector (33), and the light detector (33) is capable of properly receiving reflected light.</p> |
