Abstract

A small flexible support frame for high-stable multifunctional optical mirrors belongs to the field of space optics technology. In order to solve the problem that the existing support mechanism is only suitable for mirrors of the same material, and the use and size are limited, the flexible support frame of the present invention is Rectangular structure with a hollow circle, a rectangular convex structure mechanical connection platform of the same width is processed on both sides, two mechanical interfaces are processed at each end of the mechanical connection platform, and an optical-mechanical connection platform with a circular convex structure is processed along the hollow circle, and the optical-mechanical connection The bottom surface of the platform is processed with a concave structure, the sinking structure unloading substrate is processed between the mechanical connection platform and the optical-mechanical connection platform, and the unloading slit of the circular topological structure is processed on the unloading substrate. The integrated design of the flexible support frame is suitable for the scope of application. Wider and more adaptable for increased safety and reliability.

Description

technical field

[0001] The invention belongs to a flexible support frame for a small-sized, highly stable and multifunctional optical reflector, which relates to the technical field of space optics. Background technique

[0002] The flexible support frame is a passive adjustment structure that isolates or reduces the adverse effects on the surface shape accuracy of the optical mirror caused by factors such as temperature changes in the working environment and assembly stress through the deformation of the flexible link. This type of structure has the advantages of simple structure, no hysteresis, no crawling, and can withstand the influence of various harsh environments in space. It is currently widely used in the support structure of reflective optical mirrors in space optical loads.

[0003] At present, all spatial reflective optical mirrors use flexible structures to achieve high-precision and high-stability support designs. The closest prior art with the present inventi...
