摘要
设计了一种用于红外光电系统性能测试的目标模拟器的光学系统。原理上采用一个无焦系统与后聚焦系统的组合系统,利用Zemax光学设计软件进行优化设计,最终设计结果为工作波段8-12μm,焦距230.599mm,视场12°,入瞳距600mm,入瞳直径100mm。整个光学系统有9个光学透镜,最大口径229.77mm,光学系统达到衍射极限,全视场MTF均优于0.39,80%的能量集中在23μm的弥散圆内。各项指标都满足设计要求,能很好地应用于红外光电系统的性能测试。
We design an optical system of infrared target simulator for infrared optical testing system.A non-focal and back-focal systems were adopted.We use Zemax software to design and optimize the system.The optical system works at 8-12μm with a field of view of 12°,a focal length of 230.599 mm,an exit pupil distance of 600 mm and an exit pupil diameter of100 mm.The optical system has 9lenses.The lens with the largest diameter is 229.77 mm.The designed optical system almost achieves diffraction limit.MTF of full fields are more than0.39.80% energy is focused within 23 μm diffraction circle. The design meets the requirement.The system is good for infrared optical testing system.
