摘 要: 根据红外辐射的大气窗口特性、二元光学元件特殊的色散特性和多级衍射特性 ,提出了利用二元光学透镜的新型中波和长波红外双波段成像光谱技术 ,从理论上阐述了二元光学双波段红外成像光谱仪的基本原理和设计方法 ,实际例子证明了设计的可行性 ,利用此方法可研制轻型。 On the basis of the characteristics of the infrared radiation and binary optical elements, a novel binary optic dual-band infrared imaging spectrometer is described. The design methodology is presented and theoretical formulas are established. A practical example proves proposed method valid and feasible. It shows that the method is useful in designing compact, economical, lightweight dual-band infrared imaging spectrometer.
