Three-dimension scanning type multi-parameter laser radar system for environment monitoring

Abstract

The invention discloses a three-dimension scanning type multi-parameter laser radar system for environment monitoring. The three-dimension scanning type multi-parameter laser radar system comprises a first thermostat, a second thermostat and a three-dimension rotary bracket, wherein an optical glass window is arranged on a front end wall of the first thermostat, and a laser emitting unit and an echo signal receiving unit are arranged in the first thermostat; a signal acquisition unit, a signal processing and display unit and a power supply are arranged in the second thermostat; the three-dimension scanning is realized by the first thermostat through the three-dimension rotary bracket; the laser emitting unit is connected with the power supply through power wires; the echo signal receiving unit and the signal acquisition unit are connected with each other through signal wires; and the signal acquisition unit and the signal processing and display unit are connected with each other through electric wires. The three-dimension scanning type multi-parameter laser radar system for environment monitoring has the advantages of simple structure, running reliability, comprehensive monitoring, strong detecting capacity, capability of quickly, reliably, continuously and remotely monitoring atmospheric pollutants in real time, and relatively strong practicability.

Description

technical field [0001] The invention relates to a laser radar system, in particular to a multi-parameter laser radar system for detecting the three-dimensional space-time distribution of atmospheric particles and adaptable to outdoor complex working environments. Background technique [0002] As an advanced active remote sensing instrument, lidar can monitor a wide range of atmospheric components and environmental parameters (such as temperature, humidity, etc.) continuously, in real time, with high spatial and temporal resolution. Since the first laser came out in 1960, lidar has been widely used in many fields and has become more and more recognized due to its unique technical advantages in detection distance, temporal and spatial resolution, and long-term continuous monitoring. The laser radar system is mainly composed of three parts: laser emission, echo signal reception, data acquisition and processing. Lidar can be divided into many types according to the observation ...
