摘要
介绍大孔径静态干涉成象光谱仪的光学原理，分析基于Ｓａｇｎａｃ 型横向剪切分束器的干涉系统设计方案，推导了理论和实际的光程差公式，讨论了几种具体的结构形式，总结了各自的优缺点．
The optical principle of the Large Aperture Static Imaging Spectrometer (LASIS) is introduced The analysis of a lateral shearing interferometer system for LASIS based on Sagnac beamsplitter is presented Equations to calculate the optical path difference in both theoretical and practical situation are developed Structure and characteristics of several kinds of the embodiments are discussed
