Discrete atmosphere laser radar system based on imaging principle

Abstract

The invention provides a discrete atmosphere laser radar system based on an imaging principle. The discrete atmosphere laser radar system comprises a host and a receiver. The receiver comprises a telescope and is detachably fixed on one side of the host; the host comprises a transmitting device, a transmitting device fixed rotating plate and a bottom plate, the transmitting device is fixed on the transmitting device fixed rotating plate, and the transmitting device fixed rotating plate is rotationally connected with the bottom plate; the transmitting device comprises a laser, a reflector and a lens; along with rotation of the transmitting device fixed rotating plate, the overlapping area of the laser emitted by the transmitting device and the view field of the telescope changes. By installing the reflector, the effect of folding the optical path of the laser is achieved, the system is compact in structure, meanwhile, the receiver is mounted on the host and is easy to disassemble, and the purposes that the system is smaller in size and more portable are achieved; after the lens is focused, the position of the lens is also fixed, the integrated design of the transmitting device is realized, and the effect of convenient adjustment is achieved.

Description

technical field

[0001] The invention relates to the technical field of laser radar, in particular to a discrete atmospheric laser radar system based on imaging principles. Background technique

[0002] Aerosol refers to the general term of liquid or solid particles suspended in the atmosphere. Although the content in the entire atmospheric environment is small, it has a vital impact on human health, public health and even the environment and climate. Therefore, the detection of the temporal and spatial distribution of the optical and microphysical properties of atmospheric aerosols is of great significance to the study of regional and global environmental and climate issues. Due to the limited size range of aerosol particles, the active remote sensing technology for atmospheric aerosol detection generally refers to lidar with lasers as radiation sources. At present, atmospheric aerosol lidar generally has problems such as large size, complicated adjustment, and difficulty i...
