Polarization imaging of superficial layers of multiply scattering medium with selective localized absorber is discussed. This method is based on the analysis of polarization spectra of backscattered partially polarized light. The polarization spectra of a backscattered light are studied for phantom scattering media and for in vivo tissues. The relations between media scattering properties, the depth of absorber location, and the polarization degree as well as polarization difference reflectance spectra are discussed. It is shown that polarization degree spectra and apparent optical density spectra have the similar behavior. The depth of location of absorbing object may be evaluated by use of analysis of polarization difference reflectance spectra. This analysis can be provided on the basis of the concept of polarization decay in scattering media.
