Abstract

The invention discloses a non-strain fixing-mounting structure of an astronautic camera special-shaped prism, which comprises a left baffle (1), a special-shaped prism framework (2), a special-shaped optical prism (3) and a right baffle (5); the special-shaped optical prism (3) is mounted in the special-shaped prism framework (2); the left baffle (1) and the right baffle (5) are respectively blocked at the two sides of the special-shaped prism framework (2); strain-removing thermal treatment is carried out on the special-shaped prism framework (2), the left baffle (1) and the right baffle (5); the contact parts between the top part and the bottom part of the special-shaped optical prism (3) and the special-shaped prism framework (2) are provided with patches (4); the left baffle (1) and the right baffle (5) are provided with baffle glue injecting holes (6). As an integral opening structure is adopted by the invention, a refine linear cutting mode is adopted in processing; simultaneously strain-removing treatment is adopted to the framework structure, thus leading the strain of the special-shaped prism framework to the smallest while ensuring the processing precision, thereby avoiding the structure deformation to affect the optical performances of the prism.

Description

technical field [0001] The invention belongs to the technical field of aerospace optical remote sensors, in particular to a prism system used for mounting and fixing an aerospace optical camera. Background technique [0002] With the rapid development of aerospace optical camera technology, the resolution of optical remote sensors is getting higher and larger, and the demand for multispectral cameras is increasing, making optical prisms widely used in aerospace cameras. One aspect of the application is to meet the larger optical field of view of the camera. Since the size of the imaging device is limited in scale, a large number of devices are optically spliced ​​to meet the requirements of the camera for the optical field of view. On the other hand, it is applied to a multi-spectral camera, and a prism splitting system is used to meet the requirements of multi-spectral output. With the improvement of the performance index of the camera optical system, higher requirements ...
