摘要
介绍了双端差分吸收激光雷达的测量原理．设计了双端差分吸收全固态激光雷达，其测试对象是ＮＯ２和ＳＯ２，测试距离达１ｋｍ．
We introduced the measurement principle of
differential absorption lidar (DIAL) with a cooperative object. A all solid state DIAL system was
thus developed for measurement of NO 2 and SO 2 and detection range of 1 km. The relevent
parameters of its optical system and the design of its Q switched dual pulse dual wavelength
tunable laser system based on Cr:LiSAF was given.
