Polarization-Sensitive Spectral Interferometric Optical Coherence Tomography for Human Skin Imaging

Polarization-sensitive spectral interferometric optical coherence tomography (PS-SI-OCT) is designed for imaging of the inner structure of a biological tissue with polarization properties corresponding to Müller matrix elements. With arbitrary polarization state of incident and reference light, the change of polarization state can be acquired, and the axial structure of the tissue is measured by single detection of the power spectrum, superposition of object and reference light. Using with this OCT system, a cross-sectional Müller matrix images of human skin can be observed.
