Paper Abstract

Using developed technique for acquisition of collimated transmittance spectra (over 450 - 600 nm range, collection of transmitted light within 10-4 srad) we defined the optimum composition of the phantom (physical model reproducing optical parameters of the object) of bloodless dermis. Then the series of phantoms of different thickness was employed in testing of feasibility of gelatin gel-milk (19%) phantom for reproducing polarization properties of human skin. It was fond that the polarization degree decays two order of magnitude less intensively than intensity does, and at the thickness of the layer up to 0.4 - 0.5 mm we could expect a negligible depolarization of linearly polarized light (over 450 - 600 nm range) propagating through the tissue. This counts in favor of perspectivity of the application of polarization techniques (e.g. fluorescence) in the study of the processes occurring at fraction of millimeter depths in biotissue. But very weak decay of polarization with depth does not agree with literature data for skin slabs, this fact is attributable to the presence of significant fraction of too large scatterers in whole milk.
