| 摘 要： | 本文用随机光场自相关函数传递的方法对双曝光散斑图在全场分析光路中形成的像面光强进行了严格计算,得出了条纹对比度与滤波孔的形状和位移之间的函数关系,并以方孔和圆孔滤波为例,从实验上证明了理论结果的正确性。

| Abstract: | The transmission of autocorrelation function of random light wave was used to give the rigorous calculation of the image intensity produced by the double- exposure specklegram placed on the input plane of the filtering system, and the fringe contrast as a function of the object displacement and shape of the filtering hole was obtained. The theoretical result was verified by both square and circular hole filterings. |
