摘要：

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.
