Abstract
The invention discloses a laser radar quality control device, which belongs to the technical field of environment and meteorological monitoring equipment, solves the problem of low precision of the existing ozone laser radar, and is technically characterized by comprising: an ozone laser radar system which is used for determining ozone concentration on a common path of pulsed light, an ozone laser radar light path turning mirror, wherein the ozone laser radar light path turning mirror is arranged on one side of the ozone laser radar system, and the ozone laser radar light path turning mirror is used for observation of the ozone laser radar in the horizontal direction; a path verification module, wherein the path verification module is arranged in an area, exceeding 500m, on the transmitting and receiving optical path of the ozone laser radar, and the path verification module is used for measuring the ozone concentration; and a verification module adjusting frame which is arranged on one side of the path verification module and is used for supporting the path verification module, so that the path verification device has the advantage of higher precision.
Description
technical field [0001] The invention relates to the technical field of environment and meteorological monitoring equipment, in particular to a laser radar quality control device. Background technique [0002] Lidar is an active modern optical remote sensing device, which is an extension of traditional radio or microwave radar (Radar) to the optical frequency band. Atmospheric detection lidar uses laser as the emission light source, and detects various atmospheric elements by quantitatively analyzing laser atmospheric echo signals according to physical processes such as the scattering and absorption of laser by the atmosphere. Compared with the detection source of traditional radar, laser has the characteristics of high brightness, high collimation and short pulse, which makes lidar have high space and time resolution and high detection sensitivity, which is very suitable for atmospheric detection. probing and research. [0003] The existing ozone laser radar is based on th...
