Spatial flexible filter supporting mechanism and method for mounting filter

Abstract

The invention relates to a spatial flexible filter supporting mechanism, which comprises a mirror seat and at least three flexible supporting pieces, wherein each flexible supporting piece consists of a fixed end, an axial stress unloading part, a radial stress unloading part and an adhesive boss; the fixed ends are connected with the mirror seat through screws; the axial stress unloading parts are positioned between the fixed ends and the radial stress unloading parts; the adhesive bosses are arranged at the ends of the radial stress unloading parts; the part of the filter, which is close to the rim, is adhered with the adhesive bosses through adhesives; and the gravity of the filter is positioned in a polygon consisting of the adhesive bosses. The structural stress resistance and the thermal stress resistance of the filter supporting mechanism are improved; due to the flexible shock absorption function, the filter supporting structure can resist the impact shock at a rocket launch section, and can be used in the fields of designing aerospace and aviation filter supporting structures, designing structures of optical active supporting mirrors, designing structural shock absorption and the like.

Description

technical field [0001] The invention belongs to the field of aerospace, and relates to a support mechanism for a space optical filter, in particular to a flexible support mechanism for a space optical filter and an installation method for the optical filter. Background technique [0002] In the optical system, in order to achieve the purpose of the detector to receive light in a specific spectrum, a filter is often placed in the optical path so that the light in the working spectrum passes through the filter and enters the detector, while the light in other spectrums is absorbed by it. Reflect back. Since the filter is placed in the optical path, the front and rear end faces must be transparent, so it cannot be supported, and the support structure can only be designed by the method of peripheral support. [0003] At present, the support structure of the filter with a larger diameter is usually fixed by pressing the support of the lens holder. This method has high requireme...

Problems solved by technology

This method has high requirements on the processing precision of the mirror base, and is prone to assembly stress, resulting in poor deformation of the filter surface, and it is easy to cause the filter to be broken when encountering extreme space conditions.
