An Ultralight Carbon Fiber Remote Sensing Camera Structure

Abstract

The invention discloses a structure of an ultra-light carbon fiber remote sensing camera, comprising: a reflector assembly, the reflector assembly includes a bearing tower, the bearing tower is configured as a spliced ​​structure, one end of the bearing tower is connected with a secondary mirror, and the bearing tower The outer circumference of the tower is provided with a main reflector, and the load-bearing tower passes through the main reflector and is connected to a base plate at one end away from the secondary mirror; a shading cover can be detachably set on the outer surface of the reflector assembly; the base plate is far away from the main reflector One end is connected with a focal plane assembly; a lens assembly passing through the center of the substrate and connected to the substrate, the lens assembly is used to correct the aberration of the camera optical system. An ultra-light carbon fiber remote sensing camera structure of the present invention adopts a central load-bearing tower-type support scheme, and the center supports the secondary mirror, which reduces the overall weight of the support frame and ensures the support rigidity and surface shape of the mirror system; reduces the weight of the support frame The overall size saves space and is practical.

Description

technical field [0001] The invention relates to the technical field of space remote sensing, in particular to an ultra-light carbon fiber remote sensing camera structure. Background technique [0002] With the growth of the country's economic strength, the advancement of science and technology, and the needs of sustainable social development, China's geospatial information science and technology, including photogrammetry and remote sensing, will have a great opportunity for more rapid development in the next few years. The space remote sensing camera is an advanced optical system composed of CCD, etc., and is a sensor mounted on a satellite to obtain information on earth targets. It is widely used in resource census, topographic mapping, military reconnaissance and many other fields. With the continuous development of space remote sensing technology, the resolution of remote sensing camera to the ground has been continuously improved. Space remote sensing (especially infra...

AI Technical Summary

Problems solved by technology

The upper end of the tripod is connected to the secondary mirror, and the lower end is connected to the main mirror substrate, so that the support rigidity of the mirror system is not enough. In this case, the size of the primary mirror substrate is usually made very large, which affects further lightweight design, and the weight of the whole machine is relatively high.
