Precise polarization control based on twisted-nematic liquid crystals (TNLCs) has been proposed. We introduce a linear polarization restorer based on dynamic linear polarization rotator using a 90°-TNLC cell. By varying the applied voltages for different incident polarization directions, the precise restoration of any incident linearly polarized lights to a specified orientation is achieved.
