PROBLEM TO BE SOLVED: To provide a laser radar capable of properly detecting a distance to an object even when the distance is changed.SOLUTION: A lase radar 300 comprises: a laser source 401; a beam-shaping lens 402 for shaping the laser beam; a mirror actuator 1 for scanning a target region with a laser beam having passed through the beam-shaping lens 402; a light-receiving lens 502 for collecting light reflected by the target region; and a light detector 503 for receiving the reflected light collected by the light-receiving lens 502. A DSP 607 measures a distance to an object on the basis of a signal output from the light detector 503 and changes a distance between the laser source 401 and the beam-shaping lens 402 according to the measured distance to the object. |
