Abstract

The invention provides a laser radar and a scanning monitoring system, and relates to the technical field of radars, and the laser radar comprises a seat body, and a laser, a first reflection element, a second reflection element, a first motor, a second motor and a receiving assembly which are arranged on the seat body. A detection light beam emitted by the laser device is reflected by the first reflection element and the second reflection element in sequence and then carries out two-dimensional scanning on a target object, an echo light beam reflected by the target object returns to the second reflection element and the first reflection element in sequence and then enters the receiving assembly, and the laser device and the receiving assembly are both located on the light incidence side of the first reflection element. According to the laser radar, the emitting optical axis of the laser is parallel to the incident optical axis of the receiving assembly, so that the emitting and receiving are coaxial in the direction perpendicular to the two optical axes, a linear array receiving mode needed by an existing off-axis scheme is avoided, and the size and the cost of the laser radar are reduced.

Description

technical field [0001] The present application relates to the field of radar technology, in particular, to a laser radar and scanning monitoring system. Background technique [0002] With the development of laser technology, laser scanning technology is more and more widely used in fields such as surveying, transportation, driver assistance and mobile robots. Lidar is a radar system that uses laser light to detect the target's position, speed and other characteristic quantities. Its working principle is to first send a detection beam to the target, and then compare the signal reflected from the target with the transmitted signal, and then perform appropriate processing. , you can get the distance, azimuth, height, speed, attitude, and even shape information of the target. [0003] In the existing scheme of realizing two-dimensional scanning by setting prisms and oscillating mirrors, the emitting light source and the receiving sensor are arranged off-axis, and the receiving ...
