摘　　要：介绍了高空大气探测激光雷达的接收物镜(卡塞格伦物镜)的光路及调试方法.给出30～60km的Rayleigh回波和80～110km钠层回波信号,与原来的离轴抛物物镜的回波信号相比,具有更高的Rayleigh回波高度、更高的信号值与信噪比.Assembly and adjustment of a receiver-telescope of high atmosphere detection lidar are introduced. The results of Rayleigh return wave for 30~60km high atmosphere and the return wave for 80~110kms Na-layer are given out. Compared with the echo signal of off-axis telescope, the intensity of signal is higher and the signal-to-noise is better.
