Paper Abstract

In the paper we present method for three-dimensional measurement of birefringence distribution in anisotropic objects. The tool, which we used is combination of classic polariscopy with tomographic reconstruction method. Tomographic reconstruction is performed using the filtered backpojection algorithm. The results of measurement of glass capillary infilled with licquid crystal are presented together with the results of numerical simulation of measurement process. Simulations include polarized light propagation performed by means of finite difference time domain method combined with Jones calculus. The numerical simulations are performed for various birefringence values and allow for determination of relative errors of birefringence distribution. Additionally the absolute refractive indices are determined experimentally through the measurement of capillary with polarization sensitive microinterferometric tomography.
