Abstract

Low coherence techniques for characterization of the transport properties of dense scattering media are considered. First of them is based on optical coherence tomography performed in the A-scan mode and used to study the effects of dense packing and particle aggregation in dense layers of scattering particles (erythrocytes in diluted blood and polystyrene spheres in water) in the course of sedimentation. The second technique is based on speckle contrast analysis in the dependence on the coherence length of probe light. The additional polarization discrimination of detected backscattered light allows us to extend the functional abilities of the developed technique. With use of this method, the transport properties and the polarization decay parameters of tissues and tissue-like phantoms can be analyzed.
