Paper Abstract

The phase compensation method presented by A. Lien is a precise and convenient tool to measure the cell gap of filed twist nematic liquid crystal cells. But in the paper the equations which were used to calculate the thickness of LC layer are not enough to distinguish the two phase difference which does correspond to different cell gap. In this paper, the conditional equations were given and the factors affected the accuracy of phase compensation were discussed.
