| 摘 要： | 当漫射面发生转动时，一般情况下自由空间中的散斑图样将发生复杂的变化，但在一些特殊情况下，只发生平移变化，从波动光学理论出发对此进行了理论计算，其结果与实验观察相符。

| Abstract: | Generally,the spckle patterns observed in the free space will change because of the rotation of the diffused surfaces.Under certain circumtances,the varations of the patterns can be simplified as position displacements.In this work,authors carried out calculation for these simplified cases with the theory of wave optics.Observations indicate a qualitative agreement between theoretical predictions and experimental results. |
