Abstract
We propose a method based on an interferometric technique to measure t he molecular distortion induced by an incident light beam on a nematic liquid crystal Aim. An analysis of the fringe pattern generated by me ans of a Fourier transform method allows comparison of the measurement s with the theoretical molecular distribution. From this analysis an e stimation of the elastic anisotropy of the liquid crystal is derived w hich is in good agreement with previous results.
