Paper Abstract

In this paper we describe an interferometric technique based on high precision 2D spatial fringe analysis Fourier method for measuring the elastic constant of nematic liquid crystals. Since the determination of the elastic anisotropy relies on the measurement of the ratios between the elastic constants, this technique provides a powerful and high accuracy method for characterizing nematic liquid crystals.
