Abstract

The invention provides a mirror assembly, which includes a mirror and a supporting structure. The mirror includes a mirror body and a mirror body support part located on the back of the mirror body. The outer side of the mirror body support part is set as an outer cylindrical surface; the support structure is a split structure , comprising an outer support ring and at least three connecting blocks evenly distributed inside the outer support ring; at least one layer of flexible arms are arranged on the outer support ring, and the flexible arms are arranged along the circumferential extension of the outer support ring; organic body interface. The reflection mirror assembly provided by the invention can not only meet the requirement of low rigidity in the radial direction for temperature adaptability, but also meet the requirement of high rigidity in the circumferential direction for the reciprocating motion of the reflector in the circumferential direction.

Description

technical field [0001] The invention relates to the technical field of optical element structures, in particular to a mirror assembly. Background technique [0002] With the improvement of users' requirements on the performance of aerial optical imaging load, the optical aperture and system focal length continue to increase. Under strong constraints such as the limited design space and system weight that the carrier platform can provide, the difficulty of system design is greatly increased. Lightweight and miniaturized design has become one of the important tasks in the development of high-performance aeronautical optical imaging payloads. [0003] The mirror is one of the key components of the aeronautical optical imaging system, and its importance is mainly reflected in two aspects: (1) The optical surface shape, structural rigidity and temperature adaptability of the mirror play an important role in system transmission and environmental sensitivity. (2) The spatial layo...
