摘要
研究了同心光学系统的成像特性以及设计方法,分析了厚透镜的成像理论。设计了工作在3.7～4.8μm、视场15°的红外同心光学系统,该系统具有接近衍射极限的成像质量。对红外同心光学系统各个视场的传递函数进行了测试,结果表明该系统具有较好的成像质量,且成像特性和同心光学系统的成像原理是一致的。
The imaging principles of big field infrared concentric optical system are studied, and the imaging theories of thick lens are analyzed. An infrared concentric optical system at 3.7--4.8μm with 15 degrees of field of view is designed. The im age quality of the concentric system approaches the diffraction limit. The result of the modulation transfer function（MTF） for the system is tested and the tested value is closely approximate to the di{fractive limit and consistent with the principles of concentric optical system.
