摘要
介绍一种基于偏振原理的空间调制干涉成像光谱技术 ,对这种干涉光谱仪干涉图样的形成及其处理技术进行了理论上的分析 ,为偏振型空间调制干涉成像光谱仪的研制提供理论依据。
A novel type of spatially nodulated imaging interferometry based on polarization of birefringent crystals is intruduced.The making of four folded interferograms with different path differences is described.Furthermore,the connecting method and procedure that how to use these four interferogram to enhance the singal-to-noise and the resolving power are present.
