Supporting structure for coaxial light-small type reflecting mirror with high thermal stability

Abstract

The invention discloses a supporting structure for a coaxial light-small type reflecting mirror with high thermal stability, belongs to the technical field of aerospace, and aims to solve the problems of complicated structure, likeliness in system failure, high process level requirement and low interchangeability in the prior art. The supporting structure for the coaxial light-small type reflecting mirror with the high thermal stability comprises a reflecting mirror, a flexible joint and a core shaft, wherein an outer ring of the flexible joint is fixed with the reflecting mirror in a gluing way, and an inner ring of the flexible joint is fixed with the core shaft in a gluing way; the reflecting mirror, the flexible joint and the core shaft are coaxial; the flexible joint is of an annular structure and comprises an annulus and a plurality of single-arm structures; the single-arm structures are circumferentially and uniformly distributed on the outer wall of the annulus; each single-arm structure is a double-layer flexible unloading structure, two grooves are radially formed in the single-arm structure, and each groove is perpendicular to the diameter direction. According to the supporting structure for the coaxial light-small type reflecting mirror with the high thermal stability, a core shaft supporting mode is adopted; the external space of the reflecting mirror is not occupied; the structure is simple, and the surface shape of a mirror surface can be kept stable within a larger temperature change range; the whole optical system is convenient and quick to install and adjust, requirements on an assembly process are not high, and all parts are better interchangeable.

Description

Technical field [0001] The invention belongs to the field of aerospace technology, and specifically relates to a coaxial light, small, and high thermal stability mirror support structure. Background technique [0002] As an important component of optoelectronic equipment, the reflector determines the imaging quality of the optoelectronic system. The reflector is required to have strong resistance to external dynamic interference and small changes in the shape of the reflector. While the support structure of the reflector effectively positions the reflector, it is necessary to reduce the external interference to the reflector and the surface change of the reflector. [0003] At present, the traditional support structure applied in this field mostly adopts the method of peripheral support. Because the support point is outside the reflector, the system support structure is relatively complicated and takes up a large space, which is not suitable for the development of the system to be ...
