Skin pubic louse diagnosis depends non only on histopathological examination but in like manner on visual inspection before and after the undercut of pretend lesion. Neoplasm is accompanied with changes in birefringence of collagen, pleomorphicity, and hyperchromatic terra firma of epithelial nuclei.

These phenomena can be measured by unearthly and polarization changes of unused backscattered by the examined tissue. A new differential coefficient spectropolarimetric system is proposed using liquid crystal devices, one as a tunable ?lter and the other as a polarization rotator, both in operation(p ) at wide spectral ranges from the visible t! o the near-infrared. Since collagens ?brils grain orientation 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 hoard differential contrasts between sequenced images when simultaneously averaging the statistical readout of a characterization camera.
