Abstract

We report the method of the refractive dispersion determination in the anisotropic refractive indices in a planar liquid crystal layers. The experimental data have been obtained from transmission spectra of a plane parallel Fabry-Perot Filter (FPF) filled with the investigated liquid crystal (LC). Physical basis, experimental techniques and math procedures have been described. We assumed the perpendicular light incidence and the absence of absorption and scattering. The dispersion of both refractive indices has been determined over the visible spectrum. During the test measurement similarity of refraction index for 5 CB (K15 MERCK) with literature values has been obtained. Results for no.602 and no.1292 liquid crystalline mixtures made in Institute of Chemistry MUT are given.
