| 摘 要： | 本文用统计光学方法推导了由两个漫射体形成的串级散斑场的统计性质。得出了漫射体的运动速度v与相关时间ι_c成线性的关系,讨论了经过三次随机调制的串级散斑场的斑纹平均半径较之一次调制斑纹半径为小。理论与实验结果符合得很好。

| Abstract: | Using statistical method the statistical properties of cascade speckle through two diffusers have been developed. It was derived that the velocity of the diffuser is directly proportional to the correlation time. The average radius of triply random modulated cascade speckle, which is smaller than that of single modulated speckle was discussed. The good agreement between theoritical and experimental results is shown. |
