Abstract

The invention provides a reflector assembly, the reflector assembly includes a reflector and a support structure, the reflector includes a mirror surface body and a mirror surface body support part located at the reverse side of the mirror surface body, and the outer side of the mirror surface body support part is arranged to be an outer cylindrical surface; the support structure is a split type structure and includes an outer support ring and at least three connecting blocks uniformly distributed at the inner side of the outer support ring; at least one layer of flexible arm is arranged on the outer support ring, and the flexible arms extend along a circumferential direction of the outer support ring; and machine body interfaces are arranged on the outer support ring. The reflector assembly provided by the invention can meet a requirement of temperature adaptation to low rigidity in a radial direction, and can meet a requirement of circumferential reciprocating motion of the reflectorto high rigidity in a 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...
