| Abstract: | Based on athermal design technologies of optical passive mode,this paper describes an example of a cooled long wave infrared optical system.This system adopts a linear IRFPA with 576 pixels.Compared with old linear IRFPA with 288 pixels,the larger pixel number results in a larger field of view with same parameters such as numerical aperture,focal length,etc.The F number is 1.6,the focal length is 100mm,and the FOV is 9.2?.This system has a 100% cold-shield-match.The result shows that the image quality of th... |
