Problems solved by technology

The main reason for its high cost is that how many lines of lidar need to correspond to how many detectors, and the arrangement of multiple detectors is cumbersome, and the price is relatively expensive, so the price of multi-line lidar is expensive, and to a certain extent limit the development of civil

Abstract

The invention discloses a laser radar optical receiving system. The laser radar optical receiving system, comprises: a laser radar receiving lens used for converging an incident optical signal and focusing and outputting the incident optical signal; and a detection unit used for receiving an optical signal focused and output by the laser radar receiving lens, wherein a focal plane formed by focusing of the laser radar receiving lens is located on the receiving surface of the detection unit and is equal to or smaller than the area of the photosensitive element of the receiving surface of the detection unit. The laser radar lens in the system converges and collimates large-view-field angle information through the lens, and converges the large-view-field angle information to the laser radar receiving system of a single detector. Height information receiving perpendicular to a laser radar transmitting plane is met, the number of detectors used in a laser radar system is reduced, and the miniaturization requirement of laser radar is met. Besides, a single detection element is adopted, so that the packaging size can be miniaturized, the problem of high cost of a linear array or array detection unit is solved, and the laser radar is promoted to be truly civilian.

Description

technical field [0001] The invention belongs to the field of laser communication devices, in particular to the field of laser communication devices that can be used for unmanned vehicles, robot detection, unmanned aerial vehicle detection, automatic sweeping machines and other equipment, and specifically relates to a laser radar optical receiving system. Background technique [0002] Lidar is a radar that works in the optical frequency band. It uses the electromagnetic wave in the optical frequency band to first transmit a detection signal to the target, and then reflects it back to receive the same wave signal and transmit the signal for information processing, so as to obtain the position of the target (distance , azimuth and altitude), motion status (speed, attitude) and other information to realize the detection, tracking and identification of targets. Because lidar has high progress, strong anti-interference ability, simple structure and convenient use, it has been wide...
