Abstract

The invention relates to a positioning assembly for a back support of a mirror of an optical remote sensor, which comprises a substrate; a first fixing component arranged on the substrate and used forfixing the mirror of the optical remote sensor; a bearing component which comprises a bearing piece arranged on the substrate and a second fixing component arranged on the bearing piece; the bearingpiece is used for bearing a contact pad of the mirror of the optical remote sensor, and the second fixing component is used for fixing the contact piece on the bearing piece. According to the invention, the mirror body and the contact pad are relatively fixed through the first fixing component and the bearing component; when grinding is carried out, the grinding force directly acts on the end faceof the contact pad at the back of the main mirror component and is directly transmitted to the substrate through the bearing component, the back support piece does not bear alternating stress so as to avoid fatigue damage, and meanwhile, the grinding force when grinding the end face of the contact pad can be greatly improved so as to improve the grinding efficiency of the coplanarity grinding ofa flexible end face.

Description

technical field [0001] The invention relates to the technical field of optical remote sensors, in particular to a positioning assembly for a back support of a mirror of an optical remote sensor. Background technique [0002] The application of space optical remote sensors in the fields of earth observation and space exploration has important scientific and economic significance. Mirror components in remote sensors are the most important components in the entire optical system, and their surface shape accuracy is directly related to the image quality of the entire remote sensor. Due to the large size of the mirror surface, under the action of comprehensive factors such as gravity load, temperature load and assembly error of the mirror assembly, the mirror surface often produces serious deformation. In order to reduce the sensitivity of the surface shape accuracy of the mirror assembly to the assembly error and temperature load The support structure of the mirror assembly gen...
