摘要翻译：
我们报告了一种新型的实验，它使我们能够监测复杂流体中空间和时间上的不均匀动态特性。我们的方法是基于对光从强散射介质表面体积漫反射产生的近场散斑的分析。通过对入射散斑光束的周期调制，我们得到了结构函数系数的像素系综平均值，该系数是动态活性的一种度量。为了说明我们的方法的应用，我们跟踪胶体薄膜干燥过程中的不同阶段。我们表明，我们可以在整个视场范围内，在小到10微米的长度尺度上获得系综平均动力学性质。

英文摘要：
  We report on a new type of experiment that enables us to monitor spatially and temporally heterogeneous dynamic properties in complex fluids. Our approach is based on the analysis of near-field speckles produced by light diffusely reflected from the superficial volume of a strongly scattering medium. By periodic modulation of an incident speckle beam we obtain pixel-wise ensemble averages of the structure function coefficient, a measure of the dynamic activity. To illustrate the application of our approach we follow the different stages in the drying process of a colloidal thin film. We show that we can access ensemble averaged dynamic properties on length scales as small as ten micrometers over the full field of view.
