Dynamical correlations for multiple light scattering in laminar flow

D. Bicout , E. Akkermans , R. Maynard

A theoritical study of time dependent correlation functions of the multiply scattered light in a disordered medium is presented. We consider the situation where the fluid containing the elastic scatterers is submitted to a laminar and stationary flow. We establish a general formulation for the phase variation of scattered light originating from the motion of the scatterers within the weak scattering limit kl≫1. These results are applied to shear and Poiseuille flow as well as to plug flow of non-Newtonian fluids. The validity of the approximations used and possible extension of these results are discussed.
