Abstract

Model of polarized light interaction with anisotropic biological medium, on the example of eye cornea, is given. The polarization of the object field, which occurs during propagation through a birefringent medium, in the case of a linearly polarized incident wave, is analyzed. A polarization-interference approach for determining the polarization characteristics of the medium is proposed, which consists in analyzing the change in polarization of the field that occurs during interference of the object and reference beams. The condition of compensation of the dynamic phase allows to obtain a polarization state, determined exclusively by the geometric phase of the object field, which contains information about the polarization properties of the medium. The geometric phase value was evaluated by the geodesic triangle on the Poincaré sphere, which made it possible to restore the orientation of the optical axis (collagen fibers) of the biological medium.
