摘要：
The features of formation of interferometer output in the case of a broadband light source and a random medium as a retro-reflector in the interferometer object arm are considered. It is shown that for the large values of the pathlength difference the interferometer output decays exponentially with the decay rate dependent on the transport parameters of a probed random medium. This allows us to determine the transport mean free path of light propagation in the medium. This approach can be applied not only for strongly scattering media, but also for scattering samples characterized by non-diffusive regime of light propagation.
