Observation of anomalous transport of light in thin strongly scattering slabs

Summary form only given. Propagation of light in strongly scattering media displays many interesting phenomena such as weak localization and universal conductance fluctuations that are caused by interference of multiple scattered light. A tremendous simplification is obtained if the propagation can be described with transport theory, where all interference effects are neglected. If the sample size (L) is considerably larger than the transport mean free path I the coherent beam is suppressed and the equation of radiative transfer simplifies further to a diffusion equation. Recently, interest has arisen in medical imaging applications to determine optically the location of objects in strongly scattering biological tissues. Optical imaging may serve as an important substitute for X-ray-based techniques as optical radiation is nonionizing.
