Abstract
A surface of the tissue is illuminated with light having a known wavelength spectrum capable of materially penetrating the tissue. The light remitted from the tissue in response to the illumination is separated into at least two distinguishable polarization components. The intensity of the illumination light remitted from the tissue is measured over a hyperspectral range of wavelengths for the at least two distinguishable polarization components. Based on the preceding measurements and a degree of linear polarization of the remitted light, data representative of the three-dimensional location and one or more characteristics of an abnormal portion of the tissue are produced. Further, the masking effect of melanin may be eliminated to obtain accurate estimations of an anomaly.
