Design of Cooled Medium/Long Wave Infrared Dual-band Integrated Reflective Optical System

  • 摘要: 为避免透射式系统存在的色差问题,采用离轴反射式光学系统,在三镜后加分色片,分别成像到中波探测器及长波探测器的焦面上,实现对中波红外和长波红外两个谱段信息的同时成像。该一体化系统由3个离轴反射镜和一个分色片构成,为校正系统像差,三镜采用XY多项式曲面。采用二次成像结构形式,具有100%冷光阑效率。系统F数为2.67,视场角11.4°×1.8°,工作波段为中波3.55~3.93 μm,长波10.3~12.5 μm。中波红外系统MTF平均值大于0.5@25 lp/mm,长波红外系统MTF平均值大于0.4@12.5 lp/mm,采用光学被动式消热差法对光学系统进行温度补偿,温度适应范围为-40℃~+60℃。
