摘要: We report a liquid crystal polymer dispersion (LCPD) device that, under laser irradiation, a reflective ring pattern is observed. The observed ring pattern is due to the Qu�telet scattering light interference. Clusters of the polymer network and liquid crystal (LC) domains with various director axes serve as scatterers in the LCPD films. Changes in the first-order ring intensity are probed using a linearly polarized laser beam. Experimental results reveal that the scattering light interference ring pattern is different from that of the Fraunhofer diffraction ring pattern. The first-order ring intensity of the scattering light interference peaks if the polarization of the probe beam is parallel to the director axis of the LC molecules. The applied voltage, the order parameter and the configurations of the LCs are shown to influence the ring intensity and the polarization.
