Paper Abstract

We sometimes want to know some information hidden in highly dense media in which the light suffers a strongly multiple scattering, such as the existence of a tumor in a biological tissue and a state of a material behind a layer of paint. In such situations, optical measurement techniques which have the advantage of a non-contact and non-invasive method have been remarked and studied actively by many scientists.1 In the present paper, we pay attention to speckle-like intensity fluctuations generated by multiply scattered light and to their angular correlation properties, and investigate an effect of objects buried in highly dense media on an angular correlation function of the scattered intensity. The angular correlation function is derived theoretically and numerical simulation results are shown.
