AGHJ-I-LIDAR (HPL) typeAtmospheric particulate matter monitoring lidar (high-energy scanning series)Remote sensing detection of atmospheric particulate matter using pulsed laser with a wavelength of 532nm.

The pulsed laser enters the atmosphere after collimation and beam expansion, interacts with particulate matter in the atmosphere, and generates backscattered light. The scattered signal is received by the telescope system and converged to the optical analyzer system, forming a 532nm parallel and 532nmThe two vertical channel signals are processed by a photoelectric detection system and a signal acquisition system, and the spatial distribution (profile) of the extinction coefficient and depolarization coefficient of atmospheric particulate matter is inverted by a computer. This enables the acquisition of atmospheric quality information such as the spatiotemporal distribution characteristics of atmospheric particulate matter, spatiotemporal changes in the pollution layer, and the transport and deposition of particulate matter.
