Paper Abstract

Polarization properties of light interacting with biological tissues change depending mainly on tissue structure. In this work, a comparative method for the extraction of information about tissue structure is proposed, based on the analysis of polarization properties of liquid crystals. The Mueller matrix of the tissue is decomposed by means of the Lu-Chipman polar decomposition. As long as the scattering is weak, and so depolarization is sufficiently low, the tissue structure can be considered similar to the one of the equivalent liquid crystal. This model is applied to a sample of healthy porcine skin measured in backscattering configuration.
