我们考虑了电场的时间自相关在非均匀、起伏的混浊介质中的传输。实验是在具有空间分离的静态和动态分量的强散射介质中进行的，并且通过对沿样品表面出现的散斑场的自相关测量来获得此类介质的低分辨率动态图像。我们的分析基于场关联输运方程的扩散近似，揭示了场关联来自混浊介质中宏观动力学非均匀的散射。
We consider the transport of the electric field temporal autocorrelation in heterogeneous, fluctuating turbid media. Experiments are performed in strongly scattering media with spatially separated static and dynamic components, and low resolution ''dynamical'' images of such media are obtained using autocorrelation measurements of the emerging speckle fields taken along the sample surface. Our analysis, based on a diffusion approximation to the field correlation transport equation, reveals that the field correlation scatters from macroscopic dynamical heterogeneities within turbid media.
