Design of an airborne dual field-of-view middle wave infrared optical system
摘要
Abstract
In order to meet the practical requirement of airborne infrared searching and tracking systems, a dual Field-of-View (FOV) middle wave (MW) infrared optical system is designed based on the MW cooled detector with 320 pixel x 250 pixel and a staring focal plane array. The system adopts the secondary imaging structure and a shield is installed in the first image surface station to reduce the stray light effect. The design results show that the system has a 100% cold shield efficiency ; F number of the system keeps a constant as d and the image surface remains stable when only one piece of the optical lens is moved to switch the focus length between 800 mm and 400 mm; the field curvature and the distortion are less than 0.04 mm and 2. 5 %, respectively, and the MTF is more than 0. 5 at 16 lp/mm. Obtained results demonstrate that the image quality meets the operational requirement.关键词
