LIDAR-G-2000 Atmospheric Ozone Detection Lidar Introduction
Atmospheric Ozone Detection Lidar is based on the principle of differential absorption and uses the absorption characteristics of ozone to measure the concentration distribution of gas.
Atmospheric ozone detection lidar emits one or several pairs of different wavelength pulse detection light to the atmosphere at a high repetition rate. The selected wavelength pairs are very close, one of which is located at a position where the ozone absorption is strong, and the other wavelength is located at the ozone absorption. The position of weak or material absorption, using ozone to absorb the difference between the two laser wavelengths (difference between the two wavelengths of light signal attenuation), determine the concentration of ozone on the common path of the two pulsed lasers, thereby realizing the detection of the temporal and spatial distribution of ozone. The atmospheric ozone detection laser radar consists of three parts: the transmitting system, the optical receiving system, and the detecting and collecting system. Features
