direct-fire elbow telescope

After the characteristics of several different laser beam expanding telescope systems are analyzed,the Cassegrain system is selected to meet the design requirement of an intensive pulsed laser transmitter system.

通过分析不同激光扩束望远镜系统的特性,选用卡塞格林系统来实现强脉冲激光发射系统的设计要求,设计结果不仅满足准直性要求,并且在目标距离处的光斑大小具有一定的可调节性。
