PROBLEM TO BE SOLVED: To widen a monitoring field of a scanning type laser radar which receives reflected light of scanning laser light with a different light path from that of the scanning laser light. SOLUTION: Laser light from a laser light source 2 is scanned by a scanning mirror 4, the reflected light of which is received via a focusing lens 7 by an array of light receiving elements 8 on which a lot of the light receiving elements are arranged . A distance measuring controller 12 outputs a light receiving element selection order to a multiplexer 9 based on memory information of a conversion table memory 13 for each scanning position. According to the selection order the multiplexer 9 switches a plurality of the light receiving elements, the outputs of which are added by an output of a receiving light adding amplifier 10, and the elapsed time from the emission of the laser light to receiving the output of the receiving light adding amplifier is measured by a date measuring circuit 11. From the measured time the distance to the body A is calculated by a distance measuring circuit 12. COPYRIGHT: (C)2004,JPO
