Abstract
The alignment technique and quality check of the large mirror of the Siberian lidar station (SLS) with the diameter of 2.2 m is considered. The results of computer simulation of the field aberrations of the large mirror are presented and the area of the coma-free region is determined. The spot diagram of the large SLS mirror is measured by estimating the image size of stars passing through the zenith are presented. The numerical simulation of the lidar signal using ray tracing in the optical CAD ZEMAX is carried out taking into account the influence of a real scattering circle of the receiving optical system. The shape of the experimentally registered and ray tracing simulated lidar signal is compared.
