Problems solved by technology

For high-precision optical systems, this accuracy cannot meet the requirements
In order to improve the accuracy of assembly and adjustment, the method often used now is to improve the processing accuracy of the reflector and reduce the parallelism error of the two surfaces, which brings difficulty to the processing, and the processing accuracy cannot be infinitely improved, which limits this method of assembly and adjustment. The scope of application cannot be applied to high-precision optical systems

Abstract

The invention discloses a high-precision plane reflector adjusting method based on a theodolite. A parallelism error of the front surface and the rear surface of a reflector is removed, so that high-precision adjustment of the reflector is realized. The method is realized through the theodolite. Firstly, the theodolite is used for leading out an optical axis of a lens; then, an included angle between the two surfaces is tested through a method for self-collimating the front surface and the rear surface of the reflector by the theodolite; angles between self-collimated images of the reflectingsurfaces and the optical axis are adjusted according to a spatial position relation; and an adjusting error caused by the included angle between the surfaces of the reflector is removed. According tothe method, the problem on the adjusting precision of the reflector is solved, and the application range of the theodolite adjusted reflector is expanded.

Description

technical field [0001] The invention belongs to the field of optical technology, and in particular relates to a method for installing and adjusting a high-precision plane mirror based on a theodolite. Background technique [0002] Optoelectronic system is a comprehensive optical instrument that integrates multidisciplinary technologies of optics, mechanics, electronics, servo control, information and computer, and its development and application in the fields of national defense, military industry, aviation and aerospace are becoming more and more extensive. With the development of optoelectronic technology, the requirements for system design and installation accuracy are gradually increasing. During the installation and adjustment of optical systems, it is often necessary to precisely control the angle of the plane reflector. At present, the commonly used method is to accurately adjust the angle of the reflector through theodolite, but In the actual installation and adjustm...
