基于星载双波长偏振探测的大气探测激光雷达系统设计
Design of space-borne atmospheric detection lidar based on dual-wavelength polarization detection
摘要
Abstract
To obtain atmospheric profile of the whole world,and solve the problem that environment monitor was always restricted to a certain area,a space-borne atmospheric detection lidar was designed.This lidar working on satellite uses a 532 nm and 1 064 nm dual-wavelength laser combined with polarization detection method to obtain profile,particle size,particle shape of aerosol and cloud,and can research the requirement of three-dimensional spatial distribution detection of clouds and aerosols around the world which will improve atmospheric monitoring system.The space-borne atmospheric detection lidar used ultra-stable laser resonator to get 110 mJ laser output,and used space-borne plane etalon to get 40 pm filter bandwidth,and used high-precision pointing controller that pointing accuracy of laser beam was less than 5μrad.Finally,the paper gives test data of atmospheric vertical profiles under 15 km attitude obtained by a space-borne atmospheric detection lidar which shows dominant position of the lidar on atmospheric detection.关键词
