Abstract

Cornea anisotropic properties have been investigated experimentally by Mueller matrix technique. The system of the plane anisotropic layers has been used as an optical model of the cornea. In this model we consider every layer to be a closely packed system of long cylinders. Jones's transmission matrices of the above mentioned multilayer anisotropic system were calculated using transfer matrix 4 X 4 method. The multilayer systems with different ordering of layer's optical axis were analyzed. We have obtained spectral dependencies of limit values of linear and circular dichroism and birefringence from cornea fiber orientation. Mueller matrices of rabbit cornea were measured experimentally. Then we turn from the experimental Mueller matrix to Jones matrix to reveal clearly the cornea anisotropy. This transition is correct for the depolarization-free objects. Analyzing the cornea experimental Muller matrices by the depolarization criterion method we conclude that cornea has a negligible depolarization. Theoretical and experimental results appear to be in good agreement.
