A numerical simulation is reported of dynamic multiple (isotropic and anisotropic) scattering of light in a randomly inhomogeneous medium representing a suspension of light-scattering Brownian particles. The results of a simulation of the temporal au

A self-consistent theoretical analysis is made of the multiple scattering of coherent laser radiation in a random medium under conditions of formation of a light-induced jet of scatterers. It is shown, that the laser particle acceleration leads to a

The time correlation function of light reflected diffusely from a semi-infinite randomly inhomogeneous medium is calculated with allowance for the acceleration of the scatterers in the field of the laser beam incident on the medium. An analytical exp

We present a theoretical calculation of the modulation transfer functions and integral resolution of a simple system of imaging through the atmosphere with a finite outer scale of turbulence. Two different models of turbulence are studied. Inclusion

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 utiliz

We present the results of numerical simulation of a nonlinear optical system with a time-delayed feedback which exhibits spatio-temporal chaotic states. The model incldues three main phenomena governing the system: temporal delay, diffusion and diffr
