我们报告了在散射液体介质：不同直径的聚苯乙烯微球的稀释牛奶和水溶液中产生的斑的传输测量。散斑的大小不仅受光学厚度等散射参数的影响，还受散射体尺寸的影响。从散斑测量出发，提出了一种区分介质的方法。此外，通过蒙特卡罗模拟计算透射光剖面使我们能够更好地了解散斑尺寸的演变与散射。(C) 2004美国光学学会。
We report on measurements in transmission of the speckle produced by scattering liquid media: diluted milk and water solutions of polystyrene-microspheres of different diameters. The speckle size is affected not only by scattering parameters such as the optical thickness, but also by the dimensions of the scatters. From the speckle measurement, we propose a method to differentiate media. Moreover, a calculation of the transmitted light profile by Monte Carlo simulation allowed us to get a better insight on the speckle size evolution versus scattering.
