Brief introduction: Laser radar is a wide range of quick monitoring of atmospheric environment of a new generation of high technology. It according to the atmosphere of the laser scattering, absorption, extinction and other physical effect, through quantitative analysis, laser atmospheric echo detection for atmospheric environment. The laser has good monochromaticity, coherence of strong, high directivity and high brightness, high power. Laser high directivity and high brightness and high pulse repetition rate, the laser radar can for a few miles to a few tens of kilometers wide range real-time fast atmospheric environment monitoring; Short pulse laser makes the spatial resolution can reach several meters; Good monochromaticity, using narrow band filters can effectively improve the signal-to-noise ratio of the detection signal, which has a high detection sensitivity. By a laser radar detection data structure and time evolution characteristics of the atmospheric boundary layer can be obtained, the atmospheric aerosol extinction coefficient (fly ash) and the time evolution characteristics, cloud height and multi-layer structure, the information such as atmospheric visibility of cloud, monitoring industrial soot emissions and study their diffusion regularity, it of atmospheric environmental monitoring and atmospheric science research is of great significance, have other measure means an irreplaceable advantage. Technical parameters: Detection range: 0.03 ~ 30 km (related to weather conditions) Spatial resolution: 30 m (minimum) Works: computer control automatic operation (intermittent or continuous) Communications: networking (according to user's need) Working environment temperature: 15 ℃ ~ 30 ℃ Weight: < 30 kg (including all the equipment) laser wavelength: 532 nm (LD pumped Nd: YAG) Energy: 10 mu J p/pulse (2500 hz) The laser pulse width: 15 ns Divergence Angle: ~ 25 mu rad (half Angle) Receive telescope: diameter phi 160 mm The received view: ~ 50 mu rad (half Angle) Filter bandwidth: 0.5 nm Data collector: multi-channel counter
