AGHJ-I-LIDAR (HPL) Atmospheric Particle Monitoring Lidar (High Energy Scanning Series) Introduction
AGHJ-I-LIDAR (HPL) type atmospheric particulate matter monitoring laser radar (high energy scanning series) uses a pulsed laser with a wavelength of 532 nm to detect atmospheric particles.
After being collimated and expanded, the pulsed laser enters the atmosphere and interacts with the particles in the atmosphere to generate backscattered light. The scattered signal is received by the telescope system and concentrated to the optical detection system to form two channels of 532 nm parallel and 532 nm vertical. Through the photoelectric detection system and signal acquisition system, the computer eliminates the spatial distribution (profile) of the extinction coefficient and the depolarization coefficient of atmospheric particulate matter, and then obtains the temporal and spatial distribution characteristics of atmospheric particulate matter, the temporal and spatial variation of the pollution layer, the transport and settlement of particulate matter, etc. Air quality information.
Applications
Vertical scanning detection: spatial distribution information and spatial-temporal evolution characteristics of aerosol particles within 10 km from the ground
Regional point source/area source scanning: carry out fixed-point positioning scanning for important point sources (including overhead sources) and line sources such as chimneys, boilers, chemical plants, power plants, cement plants, and traffic trunk roads, mainly to obtain the intensity of source emission pollution.
Scanning of regional pollutant distribution: quantitative assessment of sensitive areas such as industrial parks, residential areas, and factory areas
Navigation monitoring scan: Real-time, online, continuous scanning monitoring of the input, transit and settlement processes of pollution groups above the area using the "parking scan" or "going-orientation observation" mode to analyze the type and intensity of pollutants And the evolution process
Lidar network monitoring: Through the construction of laser radar network, dynamic monitoring and tracking of air quality and boundary layer evolution characteristics in key areas can be realized, and the regional transmission process can be effectively identified. Features
