摘    要:红外成像导引头越来越广泛地采用双视场光学系统,但光学系统性能与体积之间的矛盾非常突出。通过分析导引头红外变倍光学系统和一般红外系统的区别,阐明了导引头双视场光学系统的特点,在保证性能指标的前提下,介绍了通过采取出瞳与冷屏合适的匹配方式、优化变焦结构、采取红外新技术等有效减小红外变倍系统体积的几种方法,并对其进行了公式推导和证明,给出了计算实例,同时阐明了优化总体指标,使导引头总体性能最优的观点。

关 键 词:双视场  冷屏  渐晕  匹配效率

Abstract:Dual field optical systems have been more and more widely used in infrared imaging seekers. However, the contravention between their optical performance and volume is especially evident. Through analyzing the difference between the infrared zoom and some common IR systems, the characteristics of the dual field optics systems in the seekers are described. On the premise of the same performances, several effective ways to reduce the volume of the infrared zoom systems are presented by use of the suitable matching between their exit pupil and cold shield, the optimization of the zoom configuration and some new infrared techniques. And their demonstration, formular derivation and some examples are given. In the meanwhile, the idea that the optimal collective performance should be obtained through the trade-off of various indices but not pursuing single best is illustrated.
Keywords:Dual field  Cold shield  Vignetting  Matching efficiency
