Abstract

The invention discloses an off-axis multi-reflector optical system design method based on a space coordinate transfer matrix, and belongs to the technical field of optical design. The method comprisesthe following steps: establishing an initial coordinate system and a reference coordinate system of each reflector; selecting characteristic light, establishing an input-output relationship between the reflectors, and marking intersection points between the characteristic light and the reflectors as characteristic points; realizing the transmission of light characteristics in the off-axis multi-reflection optical system through a space coordinate transfer matrix method; and finally, fitting to obtain the pose of each reflector of an off-axis multi-reflector optical system. The space coordinate transfer matrix theory is used for designing the optical system, and the integrated design and machining of the optical system and the assembly and adjustment of the system are facilitated.

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. ...
