Claim One:
1. Apparatus for obtaining characteristics of a surface of a hollow organ, the apparatus comprising: a probe configured to scan the surface of the hollow organ, the probe comprising: polarization and collimating optics configured to illuminate at least one portion of the hollow organ with polarized and collimated light having a first polarization, and light collection optics configured to receive light backscattered by the at least one portion as a result of the illumination; at least one spectrometer configured to generate at least one spectrum from the received light; an imager configured to capture at least one image of the at least one portion; and an analysis unit configured to analyze the at least one spectrum associated with the backscattered light to determine wavelength-dependent values of a reduced scattering coefficient for a sub-epithelial region of the at least one portion and to detect at least one abnormal morphological change of the at least one portion from the wavelength-dependent values.
