<P>PROBLEM TO BE SOLVED: To provide a laser radar apparatus that can achieve both a broad angle of view and a long distance of ranging. <P>SOLUTION: In an apparatus comprising: a laser beam transmitter 1 that modulates a laser beam with modulation signals and scans an object of ranging with the modulated laser beam; a scattered light receiver 2 that receives a scattered laser beam on the object of ranging by using a plurality of reception optical systems 21a and 21b having view fields different from one another and outputs electric signals representing that scattered light; and a distance intensity detecting device 32 that detects a phase difference or a time difference between the electric signals outputted from the scattered light receiver 2 and the modulated signals, an image processing device 33 calculates the distance to the object of ranging on the basis of the phase difference or the time difference detected by the distance intensity detecting device 32. <P>COPYRIGHT: (C)2012,JPO&INPIT |
