Polarization singularities of the object field of skin surface

摘要

The paper deals with the investigation of formation mechanisms of laser radiation polarization structure scattered by human skin in two registration zones: a boundary field and a far zone of Fraunhofer's diffraction. There has been defined the interrelation of optical and geometrical parameters of skin architectonics and formation conditions of polarization singularities of scattered radiation field as well. There has been studied statistical and fractal polarization structure of object fields of physiologically normal and pathologically changed skin. It has been shown that polarization singularities of radiation scattered by sound skin samples have fractal coordinate structure. It is characteristic for fields of pathologically changed skin to have statistical coordinate structure of polarization singularities in all diffraction zones.
