Title:
LASER RADAR DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/137511
Kind Code:
A1
Abstract:
This laser radar device 1 comprises: an optical system unit 20 that outputs, in the same repeating cycle, irradiation light including long pulse laser light generated by a long pulse modulator 14 and short pulse laser light generated by a short pulse modulator 15, and receives a first reflection light that corresponds to the long pulse laser light of the illumination light reflected by a first object, and second reflection light that corresponds to the short pulse laser light of the illumination light reflected by a second object; and a measuring unit 40 that calculates the movement velocity of the first object on the basis of interference light between reference light and the first reflection light received by the optical system unit 20, and calculates the distance from the laser radar device to the second object on the basis of the time from transmitting to receiving the irradiation light corresponding to the second reflection light received by the optical system.
