Abstract

The invention belongs to the space optical remote sensing technical field and discloses a lateral flexible supporting structure of a space optical remote sensor circulator reflector to solve the problem that according to the prior art, mirror surface deformation and weight waste are severe. The structure comprises three reflector body bosses evenly machined on the lateral circumference of a reflector body, and three flexible supporting units connected with the three reflector body bosses respectively. Each flexible supporting unit comprises a bonding frame, supporting arms and a supporting base, wherein the two ends of the bonding frame are connected with the supporting base through the two supporting arms, flexible grooves are formed in the four interior corners of the bonding frame respectively, a notch is formed between every two adjacent flexible grooves, four bonding surfaces are formed in the end face of the bonding frame, the four bonding surfaces are flexible relative to the bonding frame around the notches, and the bonding frame is fixedly connected with the reflector body bosses through the four bonding surfaces. According to the structure, stress generated during bonding and assembly is reduced, and it is guaranteed that surface figure accuracy of the reflector does not exceed the allowance of optical design.

Description

technical field [0001] The invention belongs to the technical field of space optical remote sensing, and in particular relates to a side flexible support structure of a circular mirror of a space optical remote sensor. Background technique [0002] The space optical remote sensor is a precise optical remote sensing system for space-based earth resource survey, space astronomical observation, geographic information mapping and national defense detailed survey and census. The basic element that usually constitutes the optical system of a space optical remote sensor is an optical mirror. The installation positioning accuracy and surface shape accuracy of the optical mirror directly affect the imaging quality of the optical system. In order to control the overall weight of the remote sensor, it is necessary to carry out a lightweight design on the reflector and control the total thickness of the reflector. This leads to a decrease in the absolute stiffness of the mirror and an...
