Skin malignant neoplastic disease diagnosis depends non only on histopathological examination but overly on visual inspection before and after the cutting out of pretend lesion. Neoplasm is accompanied with changes in birefringence of collagen, pleomorphicity, and hyperchromatic aver of epithelial nuclei.

These phenomena can be measured by spiritual and polarization changes of unused backscattered by the examined tissue. A new derivative coefficient spectropolarimetric system is proposed using liquid crystal devices, one as a tunable ?lter and the other as a polarization rotator, both(prenominal) in operation(p) at wide spectral ranges from the visible to the near-i nfrared. Since collagens ?brils grain orient! ation depends on its location in the skin and since it is not well organized, our system scans the bipolarization states by continuously rotating the linearly polarized light incident on a skin lesion, and pile up differential contrasts between sequenced images when simultaneously averaging the statistical readout of a flick camera.
