Flexible supporting structure for the back of reflecting mirror

Abstract

The invention discloses a flexible supporting structure for the back of a reflecting mirror, relating to the technical field of precision machinery for optical systems; the supporting structure comprises an upper ring (1), a lower ring (2), a first flexible element (3), a second flexible element (4) and a third flexible element (5); the upper ring (1) is fixed on the body of a camera, the lower ring is adhered to the back of the reflecting mirror, and the first flexible element (3), the second flexible element (4) and the third flexible element (5) are all positioned between the upper ring (1) and the lower ring (2) and connect the upper ring (1) with the lower ring (2). During the assembly of components of the reflecting mirror, the flexible supporting structure leads the operation simple and reliable and avoids assembling stress caused by conducting a plurality of operations to the reflecting mirror.

Description

technical field [0001] The invention belongs to the technical field of optical system precision machinery, can be applied to the back support of a reflector with an aperture below 300mm in a space remote sensing camera or a ground-based telescopic system, and relates to a flexible support structure for the back of the reflector. Background technique [0002] With the application of off-axis astigmatism optical systems in space cameras, large and medium aperture mirrors usually use multi-point back support. With the rapid development of off-axis astigmatism optical systems in space applications, small and medium aperture mirrors Back support also needs to find a solution. If the multi-point back support method adopted for the back support of large-diameter mirrors is applied to small and medium-diameter mirrors, the size of the structural parts of the back support will be reduced due to the small back area of ​​the mirror, which will cause difficulty in processing thus multi...

AI Technical Summary

Problems solved by technology

If the multi-point back support method adopted for the back support of large-diameter mirrors is applied to small and medium-diameter mirrors, the size of the structural parts of the back support will be reduced due to the small back area of ​​the mirror, which will cause difficulty in processing thus multiplying

In addition, multi-point back support requires a large area to implement. For small and medium-caliber reflectors, its occupation ratio is relatively large, which greatly reduces the degree of light weight and increases the quality of the reflector.

If the mirror is fixed in the form of a traditional outer frame, the size and thickness of the outer frame required will inevitably increase correspondingly due to the relatively large size of the mirror, which will also greatly increase the weight of the mirror
