三、设计总结 LRIRSS采用Keplerian光学系统或再成象光学系统,从Galilean光学系统或远焦光学系统的类型中已选定用Keplerian光学系统,这是因为它能够更好地控制出射光瞳。WFOV和NFOV的出射光瞳都直接安置在FLIR接收机里面的扫描镜表面上,一般来说,Keplerian系统比Galilcan系统要求更长的光路,而且利用更小的人射孔径。关于选择 Third, the design summary LRIRSS using Keplerian optical system or re-imaging optical system, from the Galilean optical system or the type of telescopic optical system has been selected with Keplerian optical system, because it can better control the exit pupil. The exit pupils of both the WFOV and NFOV are positioned directly on the surface of the scanning mirror inside the FLIR receiver. In general, the Keplerian system requires a longer optical path than the Galilcan system and utilizes a smaller man-shot aperture. About the choice
