Optical system calibration device

The invention provides an optical system calibration device, comprising a self-collimating theodolite, a calibration mirror, a light guiding arm, a base, and a plurality of optical systems. The optical system and the calibration mirror are mounted on the base. Each optical system is distributed at circumferential positions of the same radius around the position of the calibration mirror, and adjustable in angle with respect to the surface of the base. The self-collimating theodolite is aligned with the base through the calibration mirror. Light from the self-collimating theodolite respectivelyenters each optical system via the light guiding arm. The device collimates each optical system in the self-collimating theodolite by adjusting the position of the optical systems on the base, thereby keeping each optical system parallel. In addition, the device has the advantages of uniform reference, high speed, and high accuracy. 本发明提供了一种光学系统标定设备，所述设备包括自准直经纬仪、校准镜、导光臂、基座和多个光学系统；所述光学系统、校准镜安装于所述基座上，各个光学系统以校准镜所在位置为圆心、分布于相
