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.
Description
technical field [0001] The invention relates to the field of optical equipment, in particular to an optical system calibration equipment. Background technique [0002] Using optical systems for measurement is a common method. Using multiple sets of optical systems to measure the same target can measure changes in targets by identifying changes between optical systems. Therefore, the pose calibration between multiple sets of optical systems, especially The calibration of parallelism is of great significance. However, in the prior art, there are problems such as non-uniform reference, low efficiency, and poor precision for the parallelism of multiple optical systems. Contents of the invention [0003] Therefore, it is necessary to provide an optical system calibration device to solve the problems in the prior art that the parallelism calibration references of the optical system are not uniform, resulting in low efficiency and poor precision. [0004] In order to achieve th...
