Abstract

The invention discloses a detector supporting structure which is used for supporting a spaceflight optical remote sensing camera detector. The detector supporting structure mainly comprises a supporting frame body, reinforcing ribs, a diaphragm and dustproof fins, the supporting frame body is provided with an opening serving as a light inlet, the aerospace optical remote sensing camera detector is fixedly installed on the upper surface of the supporting frame body, and the reinforcing ribs are arranged on the upper surface of the supporting frame body and located on the outer side of pins of the aerospace optical remote sensing camera detector; the lower surface of the supporting frame body is provided with a diaphragm protruding downwards, the diaphragm is located on the periphery of the light inlet, dustproof fins are arranged on the outer side of the diaphragm, the diaphragm extends into the focal plane frame, and after entering the focal plane frame, external light rays sequentially pass through the diaphragm and the light inlet to reach a spaceflight optical remote sensing camera detector. According to the invention, the rigidity of the spaceflight optical remote sensing camera detector supporting structure is improved, the influence of stray light on the detector is reduced, and the dustproof effect is excellent.

Description

technical field

[0001] The invention belongs to the technical field of aerospace optics remote sensing camera detectors, and in particular relates to a support structure that can be used for space high-resolution camera detectors. Background technique

[0002] Space optical remote sensing camera detectors usually use the detector support structure as the detector support structure, and connect with the focal plane frame through the detector support structure. The installation accuracy of the detector on the focal plane frame requires 1um~1.5um The stiffness of the structure is critical. Aerospace optical remote sensing cameras have higher and higher requirements for stray light, and the design of stray light inside the focal plane is an urgent problem to be solved. The pixel size of most detectors is less than 10um, which requires extremely high cleanliness. When the detector is imaging, the redundant objects exceeding the pixel size will seriously affect the imaging qualit...
