Abstract

The invention discloses an off-axis multi-reflection optical system design method based on a space coordinate transfer matrix, belonging to the technical field of optical design. This method establishes the initial coordinate system and reference coordinate system of each reflector; selects characteristic rays, establishes the input-output relationship between each reflector, and records the intersection point between the characteristic rays and each reflector as a feature point; The method realizes the transmission of light characteristics in the off-axis multi-reflection optical system; finally, the pose of each mirror in the off-axis multi-reflection optical system is obtained by fitting. The invention uses the space coordinate transfer matrix theory to design the optical system, which is beneficial to the integrated design, processing and system assembly and adjustment of the optical system.

Description

technical field [0001] The invention relates to the technical field of optical design, in particular to an off-axis multi-reflection optical system design method based on a spatial coordinate transfer matrix. Background technique [0002] With the advancement of space optical remote sensing and aerospace technologies such as rockets, satellites, and space stations, the design and processing technical indicators of optical systems are getting higher and higher, and high resolution and wide coverage have become increasingly urgent needs. However, the contradictory relationship between high resolution and large field of view limits its development to some extent. The early optical systems all used the refraction system. With the research on optical design theory and reflective system, the catadioptric system and all-reflective system gradually appeared. Then higher resolution and less energy loss became an urgent problem to be solved, thus producing off-axis optical system. ...
