Paper Abstract

A great variety of tissues can be distinguished on the basis of its response to illumination with polarized light. In this study we used a phase resolved polarization sensitive optical coherence tomography (PS-OCT) system to investigate depolarization effects of different human tissues. The instrument which is based on a transversal scanning of the sample measures backscattered intensity, retardation and fast axis orientation, simultaneously. Skin, iris, and retina of healthy human volunteers were measured with our system. A depth resolution down to few micrometers could be achieved in skin and anterior eye segment. Different tissues could be classified into birefringent, polarization preserving and depolarizing tissue.
