Paper Abstract

A simple interferometric technique is developed to study the weakly anchored nematic liquid crystal behaviour. The Freedericksz transition threshold and the thickness of the wedged nematic sample are measured by recording its birefringence fringe pattern as a function of angles of incidence of the input beam and its optic axis. These values have been used to determine the anchoring energy coefficients.
