EA071 Atmospheric Abient particulate matters laser radar monitor

Brief introduction

Atmospheric particle monitoring laser radar is based on the principle of M. Radar emitting at 532 nm and 355 nm laser, reception of the telescope to collect the aerosol and cloud of incident laser scattering signal, 355nm echo signal and 532nm the vertical and the horizontal polarization signal through the receiver and analysis of particle extinction properties and the polarization properties to identify particulate matter of temporal and spatial distribution and the identification of dust and cloud, local pollutants.

Features

The design of the laser beam with a single pulse energy is high, which can effectively improve the detection range, time resolution and spatial resolution of the laser radar;

Dual wavelength detection 355nm+532nm and effectively obtain the particle size distribution of information, to achieve the smaller size particles of possession of ratio detection, in response to the smallest particle of radius 5 nm.

Polarization channel design, can effectively identify the types of particles;

Multi wavelength extinction coefficient inversion algorithm, obtain more accuracy;

The unique structure of the coaxial transceiver, effectively prevent the low scattering signal caused by detector saturation;

Highly automated detection, control components of IPC to open and close, support long time unattended, suitable for business operation;

The software has a friendly user interface, convenient staff for local or remote operation; the monitoring results can be generated automatically, without post-processing, convenient use and management;

Perfect collection and post data processing software by computer, convenient storage and transmission of data collection, data acquisition software can provide the function of data acquisition and interface with remote;

Software can be graphic display lidar echo signal profile, atmospheric boundary layer height, back partial ratio, extinction coefficient, back scattering ratio, optical thickness, PM10, spatial and temporal evolution characteristics, wavelength exponent distribution, cloud type, cloud height, cloud base height, visibility and particulate transport flux, on sand dust storm warning.
