Imaging Mueller polarimetry for probing biological tissue at macro- and microscale

Summary
It has been proven that polarized light is extremely sensitive to tissue microstructure. Early pathological changes in tissues may not be visible with a naked eye. This contrast, however, can be increased in polarized light images, because these changes alter fine fabric of healthy tissue. Consequently, the polarimetric maps of tissue depolarization, retardance and diattenuation may serve for a non-invasive tissue diagnosis and following treatment. The results of our studies of biological tissues (brain, stomach, uterine cervix) using imaging Mueller polarimetry at both macro- and microscale and appropriate data post-processing algorithms will be presented and discussed.
