Abstract
Using the image square scanning mechanism, a large field of view infrared optical system is designed. The field of view of the optical system is increased by 16 times compared with the theoretical value. It has the characteristics of small size, light weight and simple structure. The working spectral region is 8~12μm, the focal length is 90mm, the scanning field of view is ±24°, and the instantaneous field of view is 3°. The system has image quality close to the diffraction limit in the full field of view, and can be applied to photoelectric reconnaissance systems with miniaturization requirements to solve the problems of future high-speed and miniaturization.
