Abstract

The techniques for alignment and quality checking of the primary 2.2-m diameter mirror of the Siberian lidar station (SLS) are suggested. The results of computer simulation of the field aberrations of the primary mirror are presented, and the area of the coma-free region is estimated. The spot diagram of the SLS primary mirror is measured based on the estimates of the image size of stars transiting through the zenith. Lidar signals are numerically simulated using ray tracing in the optical design program ZEMAX, accounting for the effect of the real spot diagram of the receiving optics. The shapes of the experimentally recorded and ray tracing simulated lidar signals are compared.

西伯利亚激光雷达站主镜的对准技术和质量检查

摘要

建议对西伯利亚激光雷达站（SLS）的2.2毫米直径主镜进行对准和质量检查的技术。给出了主镜场像差的计算机仿真结果，并估计了无昏迷区域的面积。SLS主镜的点图是根据对穿过天顶的恒星的图像大小的估计值进行测量的。在光学设计程序ZEMAX中使用光线追踪对激光雷达信号进行了数值模拟，这考虑到了接收光学器件的真实点图的影响。比较了实验记录和射线追踪的模拟激光雷达信号的形状。
