【Abstract】 An experimental method of measuring the birefringence effect in liquid crystal cell is introduced. By using such a method,the anchoring direction and the twist angle of the liquid crystal cell can be basically determined. The possibility of using this method to calibrate the polarized direction of a polaroid is also discussed.更多还原
