The polarization conversion of a twisted nematic liquid crystal device can be completely characterized by the physical parameters, including the cell parameters and equivalent birefringent parameters. Periodic ambiguity is unavoidable in the measurement; therefore, the exact values of these parameters cannot be uniquely determined. To solve this problem, phase-shift imaging polarimetry is developed...
Photo-alignment method is proposed to obtain the prefect spherically symmetric liquid crystal director orientation using Ti:sapphire laser beam direct writing on the alignment layer. The micrograting pattern with period of sub-micrometer can be observed inside the laser curing route of the photopolymer film.
