Coaxial installation and adjustment system and installation method of multi-field sensor optical system

Abstract

A coaxial installation and adjustment system and method for multi-field sensor optical systems, the installation and adjustment system includes an autocollimation light pipe, a first plane reflector, a dihedral mirror assembly, a centering connection cylinder, and an adjustment chuck and the headstock of the centering lathe; the adjusting chuck is arranged on the headstock of the centering lathe; the dihedral mirror assembly includes a lens barrel, a plane reflector, a pyramid reflector and a connecting flange arranged on the lens barrel in turn; the connecting flange is provided with The flange hole and the connecting end face; the adjusting chuck is fixedly connected with the lens barrel of the dihedral mirror assembly through the centering connection cylinder and drives the dihedral mirror assembly to adjust the position; the first plane reflector is arranged on the The light path where the outgoing light is located; the pyramid reflector of the dihedral mirror assembly is arranged on the light path where the reflected light formed after being reflected by the first plane reflector is located. The invention has the advantages of improving coaxial precision, reducing operation difficulty and shortening the assembly and adjustment cycle.

Description

technical field [0001] The invention belongs to the field of optics, and relates to an adjusting system and an adjusting method of an optical system, in particular to an adjusting system and an adjusting method for a coaxial optical system of a multi-field sensor. Background technique [0002] Since the 1990s, people have continuously launched an impact on space research, especially in the exploration of the moon. Countries are in a state of vying for each other, and our country's lunar exploration activities are in a very important position. The ultraviolet moon sensor is a large field of view imaging optical attitude sensor with the moon as the attitude reference source. Its combined optical system has a central field of view with a field of view of 30° and a circular field of view with a field of view of 120° to 160°. To achieve such a large field of view while ensuring good imaging quality, the optical design, processing and adjustment are very difficult. In order to i...

This results in non-surface contact between the octagonal pyramid and the bottom plate, causing the stress to act on the octagonal pyramid, resulting in a change in the shape of the reflective surface of the pyramid.

This approach introduces optical distortion and system instability to the system
