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

These phenomena can be measured by ghostlike 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, two in operation(p) at wid e spectral ranges from the visible to the ne! ar-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 salt away differential contrasts between sequenced images when simultaneously averaging the statistical readout of a goggle box camera.
