摘要
在多环检测系统理论的基础[4,5]上,通过对激光天线单镜和双反射镜的高斯光束的传播规律和双镜距控制光斑稳定不变的实验数据[1,2],来进行激光天线的设计。设计采用了高斯光束控制入射光束的光腰位置,对天线副镜和主镜的入射角、反射角和天线发散角的控制方法,设计了天线的副镜和主镜的曲率半径、焦距和直径,达到了光斑保持的目的。计算公式简单,使用方便,计算公式和实验测定的数据误差在工程设计要求的范围以内,适合工程设计的需要。
Based on the multi-ring detection system,the curvature radius and the focal distance of the double lens of the laser antenna have been designed for the laser antenna through the propagation role of Gaussian beam,and the experimental data of the preservation method of light spot by the adjustment of the distances of double lens to control the position of the light waist,and the incident angles reflective angles and emitted angles of the laser antenna,in which the preservation of the light spot has been kept in good state.The radius of curvature and focal lens and diameter are designed.The formula for design is very simple convenient for using.The calculation result is agreed with the experiment and error is within the requirement of engineering design.
