Propagation de la lumière en milieu aléatoire. Rôle de l'absorption, de la diffusion dépendante et du couplage surface-volume

Abstract : The study of light propagation through scattering media has long been a broad field of both fundamental and applied research. It can be used to model the transport of waves in general and can be applied in the evaluation of radiative properties of coatings (like scattering paints), or imaging through diffusive media (biologic tissue) etc.

Propagation of waves can be modelled by the Radiative Transfer Equation (RTE). The majority of this PhD thesis deals with the fundamental evaluation of the RTE parameters when the random medium contains high volumic fraction of hard particles that are immersed in an absorbing host medium. This problem is solved by using the multiple scattering theory and its link with RTE. The last part of the thesis considers the problem of media that scatter the light due to rough surface and inhomogeneous volume.
