散射板干涉仪生成条纹的统计模型

A Statistical Model of Fringe Formation of Scatter Plate Interferometer

从傅里叶光学与统计光学原理出发，对散射板干涉仪的基本光路进行了严格分析．用傅里叶光学方法证明先散射后透射与先透射后散射２条光路传播光的等价性．

The basic optical path of scatter plate interferometer is strictly analysed by using the principles of Fourier optics and statistical optics.With the basic principles of Fourier optics,the equvilance of the two optical paths on propagating light:the scattered direct path and the direct scattered one is proved.With the principles of statistical optics ,the creation of interference fringes and its contrast with relation to transmitivity correlation between the two scatter plates is explained.
