Abstract

True borders of certain skin cancers are hard to detect by the human eye. For this reason, techniques such as polarized light imaging have been used to enhance skin cancer contrast before Mohs surgery procedures. In standard polarized light imaging the effect of the rough surface is minimized using a matched boundary, such as a glass slide and gel. Moreover, the surface glare is eliminated using skewed illumination. In this paper, we study the effect of the surface roughness on the polarized light backscattered from the skin. We demonstrate that rough surface effects can be minimized using out-of-plane polarized illumination in conjunction with polarized viewing.
