Abstract

The invention discloses an infrared imaging system adopting an inflatable film reflector and a compensating mirror thereof. The infrared imaging system includes a film mirror, an optical path compensation mirror group and a detector. The parallel light beam emitted from the object space is transmitted through the first polyimide film of the film mirror and then incident on the second polyimide film. After being reflected by the second polyimide film, it is transmitted through the first polyimide film again and then enters the optical path compensation mirror group, and the light beam compensated by the optical path compensation mirror group finally enters the detector for ideal imaging. The invention adds an optical path compensation mirror group in front of the detector, which cooperates with the film reflector to effectively eliminate the surface shape error between the actual surface shape of the film reflector and the ideal spherical surface, so that the surface shape of the film reflector can achieve ideal imaging requirements; the process is simple and the operation is convenient, which can not only improve the surface shape accuracy of the thin film mirror, but also improve the imaging quality of the thin film mirror.

Description

technical field [0001] The invention belongs to the technical field of optical imaging systems, and relates to an infrared imaging system using an inflatable film reflector and a compensation mirror thereof. Background technique [0002] With the rapid development of aerospace and military reconnaissance technology, the requirements for ultra-large and ultra-light optical mirrors are becoming more and more urgent. Thin film mirrors are space optical systems that use a flexible polymer film as the base and form the required curved surface in a certain way. It has the advantages of large aperture, low surface density, and low cost, effectively solving the contradiction between the large aperture and low weight of the space mirror. Therefore, its development is of great significance to the development of space technology and military reconnaissance capabilities. [0003] Inflatable film mirrors usually use polyimide film as the film material, which is an optical system that u...
