摘要
当漫射表面发生转动时，像面散斑将发生复杂变化，即使转动角度较小，前后两个散斑图也不只是发生平移的简单关系．
Rotating the deffused sarface will induce complicated changes in the speckle patterns of image plane.Even the rotating angle is very small,these changes can not be simply attributed to the displacement of the patterns.In this work,these complicated changes have been calculated with the Fresnel diffraction theory.
