Multi-angle differential absorption device based on laser radar

Abstract

The invention discloses a multi-angle differential absorption device based on a laser radar. The outer side of a differential absorption laser radar body is provided with an enlarged reflection assembly, a bottom cover is sleeved at the bottom end of the differential absorption laser radar body, the top surface of a plastic film is bonded with a reflection film, and the bottom end of the bottom cover is provided with a lubricating oiling assembly; an adjusting assembly is installed at the bottom end of the differential absorption laser radar body, a positioning supporting assembly is connected to the bottom end of the base in a sleeving mode, and an adjusting screw rod is connected with a supporting ring in a penetrating mode through threads. Reflecting electromagnetic waves of a reflecting film of the enlarged reflection assembly are used, so that the differential absorption laser radar body can receive more information by means of reflection, a positioning supporting assembly and a adjusting assembly are used, so that the device is better attached to the ground and prevented from sliding in the placing process, the adjusting assembly adjusts the angle and position of the radar to be horizontal, normal work of the radar is facilitated, and the best adjusting and using effect is achieved through cooperation of the enlarged reflection assemblyand the lubricating oiling assembly.

Description

technical field [0001] The invention relates to the technical field of laser radar, in particular to a multi-angle differential absorption device based on laser radar. Background technique [0002] Lidar is a radar system that emits laser beams to detect the position, speed and other characteristic quantities of the target. Lidar is an advanced detection method combining laser technology and modern photoelectric detection technology. Lidar detects air pollutants. The fields of chemistry, atmospheric radiation monitoring and analysis, and climate forecasting are playing a pivotal role. [0003] In the patent application number 201811513928.4, "a differential absorption laser radar that can be adjusted at multiple angles" is mentioned. At the same time, the locking mechanism is added to effectively fix the differential absorption lidar to ensure the accuracy of the monitoring results. However, during the use of the radar, due to the fixed shape of the radar area, when receivi...
