RECEIVING APPARATUS, LASER RADAR COMPRISING SAME, AND DETECTION METHOD

WIPO Patent Application WO/2022/127078

A1

A receiving apparatus (10) applicable to a laser radar. The receiving apparatus comprises: a receiving optical assembly (11), which is configured to receive and converge an echo (L1), reflected by a target object, of a detection beam of a first band emitted by a laser radar, and a beam (L2) of a second band, wherein the second band does not comprise the first band; a light-splitting unit (12), which is arranged downstream of a light path of the receiving optical assembly (11), and is configured to split light paths of the reflected echo (L1) of the detection beam and the beam (L2) of the second band; a detection apparatus (13), which comprises at least one group of detection units (131), is arranged downstream of a light path of the light-splitting unit (12), and is configured to receive the reflected echo (L1) of the detection beam from the light-splitting unit (12) and convert same into an electrical signal; and an imaging apparatus (14), which comprises at least one group of imaging units (141), is arranged downstream of the light path of the light-splitting unit (12), and is configured to receive the beam (L2) of the second band from the light-splitting unit (12) and perform imaging.
