Mueller matrix imaging polarimetry - for tissue imaging

Polarimetric Imaging is an emerging technique that uses polarized light to probe the physical and physiological properties of tissues. Polarization Ellipsometric techniques are utilized to understand the variation of polarization properties of light through sample tissue. The obtained optical signature matrix helps clinicians understand and assess the tissue properties and provide knowledge about the functioning of the tissue. In our work tissues collected from pathology lab of Gandhi Medical College, Hyderabad, India is used for recognizing the signature matrix of the tissue. Conditions to obtain a recognizable Mueller Matrix with rotating optics are addressed and are used to understand the polarization variation in the tissue through a novel pixel by pixel analysis technique and via the normalized signature matrix of the tissue.
