Abstract

Starting from the experimental channeled spectra I of the nematic EBBA liquid crystal and using a nonlinear optimization algorithm, we computed the dispersion curves of the ordinary and extraordinary indices, of the birefringence and the band contributions to these dependencies, as functions of the temperature. The theoretical interpretation of the spectra and the data processing technique allowed us to compute the realistic variation of the order parameter S and correction factor g with the same external parameter.
