Problems solved by technology

In the coaxial four-reflection optical system, the main mirror and the four mirrors are usually installed back to back. In order to ensure the surface shape of the main mirror and the four mirrors, it is necessary to design a supporting structure with sufficient rigidity for the main mirror and the four mirrors. The total mass and axial size of the mirror and the four mirrors are larger, requiring greater launch resources

Embodiment Construction

[0017] In conjunction with accompanying drawing and example, the specific embodiment of the present invention is described in further detail:

[0018] An integrated double-sided mirror is designed, in which two large mirrors are back-to-back and share the same support structure, specifically including A mirror 1, B mirror 2 and a closed plate 3.

[0019] A reflector 1 is made of silicon carbide, the front is a mirror surface, the thickness is 6mm, the back is a triangular lightweight structure, the thickness of the rib plate is 3mm, and there are 36 installation holes uniformly arranged on the back;

[0020] Mirror B is made of silicon carbide, the front is a mirror surface, the thickness is 6mm, the back is a triangular lightweight structure, the thickness of the rib plate is 3mm, and there are 6 installation holes evenly distributed on the inner circumference, and there is a hollow cavity inside, which is convenient for installing the support structure through;

Abstract

The invention discloses an integrated double-sided mirror. The integrated double-sided mirror comprises a reflecting mirror A, a reflecting mirror B and a sealing plate. The reflecting mirror A is connected with the sealing plate, and the assembly is connected with the back face of the reflecting mirror B. The front surfaces of the reflecting mirror A and the reflecting mirror B are reflecting mirror surfaces, the middles adopt triangular lightweight structures, and the backs are provided with mounting holes to be connected with an external support. According to the invention, the two reflecting mirrors are designed into an integrated structure in a back-to-back manner, so that the mass of the mirror body is reduced, the axial size space is saved, a larger aperture and a larger focal length can be obtained under the condition of the same size, and higher popularization value is achieved in the field of space loads.

Description

technical field [0001] The invention relates to the field of satellite payloads, in particular to an integrated double-sided mirror. Background technique [0002] In order to achieve large field of view detection, large-aperture remote sensing cameras will use a coaxial four-reflection optical system. In the coaxial four-reflection optical system, the main mirror and the four mirrors are usually installed back to back. In order to ensure the surface shape of the main mirror and the four mirrors, it is necessary to design a supporting structure with sufficient rigidity for the main mirror and the four mirrors. The total mass and axial size of the mirror and the quadruple mirror are larger, requiring greater launch resources. In the present invention, two mirrors are designed back to back as an integrated structure, which reduces the quality of the mirror body and saves the space in the axial dimension. Under the same size, a larger aperture and focal length can be obtained, ...
