Problems solved by technology

However, since the flexible bearing structure of the fast mirror cannot always be in full contact with the mirror holder, there will be a gap between the flexible bearing structure and the mirror holder, especially when the mirror holder moves, this gap is inevitable
The existence of this gap affects the pointing accuracy of the fast mirror

Abstract

The invention provides a serial-connected load carrying type rapid reflector structure. A flexible support is taken as a structure directly contacted with a reflector frame to constraint the free degree of a rapid reflector. A ball is arranged in the tail hole at the bottom end of the center fixing column of the flexible support, a rigid support formed by a ball seat and a compression spring adjusts the gap between the flexible support structure and the reflector frame, and the gap between the reflector during the motion and the reflector frame can be reduced, so that the rough adjustment of the deflection position of the reflector is realized. A position sensitive device receives the position signal of the reflector and feeds the signal back to a control system, a voice coil motor receives the instruction signal from the control system, so that the fine adjustment of the position of the reflector can be realized. The reflector frame is directly pushed by four voice coil motors that are staggered with the position sensitive device, so that the whole structure is compact.

Description

technical field [0001] The invention belongs to the technical field of optical-mechanical structure design, and in particular relates to a fast reflective mirror structure, in particular to a fast reflective mirror in which a flexible element and a rigid element are carried in series in a support structure. Background technique [0002] Fast mirrors are devices that can precisely control beam deflection. Due to their advantages such as fast response speed, high operating bandwidth, and high pointing accuracy, they are widely used in astronomical telescopes, adaptive optics, and free-space optical communications. Research hotspots at home and abroad. [0003] The bearing forms of fast mirrors mainly include rigid bearing and flexible bearing. Compared with the rigid load-bearing fast mirror, the flexible load-bearing fast mirror uses the deformation of the flexible unit itself to constrain the degrees of freedom of the fast mirror, and has the characteristics of no friction ...
