Multiple scattering of laser radiation in a randomly inhomogeneous turbid mediumwith a spatially localized flow of particles is studied. The timeautocorrelation function of backscattered light is calculated for the case of alaminar flow of scatterers in a cylindrical capillary embedded in the medium. Anew method is proposed and tested experimentally for determining the position ofthe dynamic region and the dominant form and characteristic velocity of theparticle motion there.
