Abstract

Fundamental properties of phase modulation ability of a nematic liquid crystal cell is first studied. Based on the phase modulation property of the liquid crystal cell, a new type of speckle shearing interferometer is proposed and studied experimentally. In the method, a liquid crystal cell is employed as a phase shifter to implement the phase shifting method for the conventional speckle shearing interferometer. From the experiments to measure the deformation of an object, usefulness of the method is confirmed.
