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 theodolite-based high-precision plane reflector assembly and adjustment method, which realizes the high-precision adjustment of the reflector by removing the parallelism error of the front and rear surfaces of the reflector. Wherein said method is realized by the theodolite, at first the theodolite draws the optical axis of the lens, secondly by the method of theodolite respectively self-collimating the front and rear surfaces of the mirror to test the angle between the two sides, adjust the self-collimation image and the optical axis of the reflecting surface according to the spatial position relationship This method solves the problem of the adjustment accuracy of the reflector and expands the scope of application of the theodolite to adjust the reflector.

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...
