<P>PROBLEM TO BE SOLVED: To provide a laser radar capable of accurately measuring a distance to an obstacle, without increasing a circuit scale, when stray light is incident thereon. <P>SOLUTION: A laser radar 1 comprises a laser light source 21 for emitting a laser beam, a mirror actuator 23 for scanning the laser beam in a target area, a light detector 33 for receiving the reflection light of the laser beam reflected in the target area, and a light detector driving unit 34 for moving the light detector 33. The light detector driving unit 34 moves the light detector 33 to an incident position of the reflection light. By moving the light detector 33 to the incident position of the reflection light, the reflection light can be accurately detected without using a plurality of light detectors and circuit units. <P>COPYRIGHT: (C)2012,JPO&INPIT |
