Abstract :
We have measured non-invasively the liquid flow changes by using a photon correlation spectroscopy with a simple correlation diffusion model for studying and monitoring the dynamic nonhomogeneities in a random high scattering media. The method utilizes the Doppler broadening of light that arises in a multiply scattering dynamic medium, and is also responsive to changes in the absorption and scattering coefficients. Our measurements clearly show the flow changes that qualitatively agree with the theory
