Document Type and Number:
WIPO Patent Application WO/2021/083016
Kind Code:
A1
Abstract:
Disclosed is a laser radar (100), comprising: a laser (101) configured to be capable of emitting a laser beam; a transmitting lens (102), which is arranged downstream of a light path of the laser (101) and configured to be capable of emitting a detection light beam after shaping the laser beam, wherein the transmitting lens (102) is provided with an aperture diaphragm area; a receiving lens (103), wherein the receiving lens (103) is configured to be capable of receiving a light beam obtained after the detection light beam is reflected outside the laser radar; and a compensation lens (104), which is arranged in the aperture diaphragm area of the transmitting lens (102) and configured to be capable of receiving at least part of the laser beam and/or the detection light beam and deflect the received light beam towards the receiving lens (103).
