Low-coherence interferometry in random media. I. Theory.

Abstract
We present a new nonperturbative theoretical method for the analytical description of light propagation in random multiscattering media. The method is illustrated through the calculation of an expression that describes optical backscattering from a semi-infinite disordered medium. A companion paper [J. Opt. Soc. Am. A 17, 2034 (2000)] compares the theoretical expression with experimental data.
