介观斑点
Mesoscopic Speckle
摘要：
我们已经测量了奇异速度v的局部和全局统计数据，并通过v的空间关联函数将这些数据关联起来。v的分布是散斑图案中全局变化的介观分布和高斯随机场v的分布的混合物。当v用分数光强变化的标准差归一化时，v的概率分布和关联函数接近随机高斯场的概率分布和关联函数。这些结果直接类似于由总透射归一化的透射强度的统计，并且为理解散斑演化和强度的统计提供了统一的框架。
英文摘要：
We have measured the local and global statistics of singularity velocity, v, and have related these through the spatial correlation function of v. The distribution of v is a mixture of a mesoscopic distribution of global change in the speckle pattern and the distribution for v for Gaussian random fields. When v is normalized by the standard deviation of the fractional intensity change, probability distributions and correlation function of v approach those for random Gaussian fields. These results are directly analogous to the statistics of transmitted intensity normalized by the total transmission and provide a unified framework for understanding statistics of speckle evolution and intensity.
