Abstract

The invention relates to the field of spaceflight optical remote sensors, and particularly discloses a tooth-shaped reflector integrated supporting frame structure with high force thermal stability, which comprises a reflector and a supporting frame, and a plurality of supporting grooves are formed in the supporting surface of the reflector. The supporting groove extends in the direction close to the axis of the reflector along the edge position of the supporting face of the supporting groove of the reflector, the supporting groove comprises a bottom wall, an end wall and two side walls, the bottom wall is located on the supporting face of the reflector, and the end wall extends in the direction parallel to the axis of the reflector from the end, close to the axis of the reflector, of the bottom wall. The side walls are located on the two sides of the bottom wall and the end wall, the side, facing the reflecting mirror, of the supporting frame is provided with a plurality of supporting teeth, the supporting teeth are clamped in the supporting grooves, adhesive layers are arranged between the supporting teeth and the bottom wall and between the supporting teeth and the side walls and between the supporting teeth and the end wall, and the effects that the surface shape of the reflecting mirror can be easily kept, large vibration loads can be borne, and high temperature adaptability is achieved are achieved.

Description

technical field [0001] The present application relates to the technical field of aerospace optical remote sensors, in particular to a toothed reflector integrated bracket structure with high thermal stability. Background technique [0002] Reflector is the most critical optical component in the optical system of space remote sensing camera, and its surface shape accuracy has a direct impact on imaging quality. The space remote sensing camera must bear the shock, vibration and overload in the process of carrying and launching, and also bear the influence of space temperature changes, and must ensure the surface shape and position accuracy of the optical components of the optical system. Therefore, the supporting mechanism of the mirror is required to ensure the stability of the position and surface accuracy of the mirror. [0003] With the improvement of the resolution of the space camera, the diameter of the main reflector is getting larger and larger. When the diameter of ...
