The spatially modulated polarization interference imaging spectroscopy (SMPIIS) is based on the polarization interferometer.The core of the polarization interferometer is the Savart polariscope. When light passing through polarizer,the natural light becomes linearly polarized in the direction of the polarization orientation of a linear polarizer. The linearly polarized ray is split into two polarized components by a Savart polariscope. After going through the analyzer,the two rays get linearly polarized in the polarized orientation of the analyzer and are focused by the imaging lens to form the interferogram and target image. From analyzing the mechanism of formation the interferogram and target image,we find the discrete between ordinary ray (o-ray) and extraordinary ray (e-ray) greatly influence the intensities and the results of the interferogram and target image. The wave vector of e-ray is obtained by the extension of Snell's law in the Savart polariscope. According to the relation between the wave vector of e-ray and e-ray,the direction of e-ray is solved. After the directions of o-ray and e-ray are given, the formula of the discrete between o-ray and e-ray can be got by calculating.
