摘要
介绍基于横向剪切干涉仪的大孔径静态干涉成象光谱仪的原理，用坐标变换和矢量分析的方法计算空闪光线的光程差，通过计算机仿真归纳出横向剪切干涉仪空间光线光程差的一般表达式．
Large Aperture Static Imaging Spectrometer (LASIS ) based on Latefal ShearingInterferometer is introduced to illuminate the necessary of calculating optical path difference ofviewfield ray from any direction in Lateral Shearing Interferometer. Coordinate transform and yector analysis are used in the calculation taking Sagnac interferometer as an example of Lateral ShearingInterferometer. Formula to calculate the optical path difference is obtained by the analysis of computeremulating experiments.
