Abstract
In order to get linearly-controlled variable retarder, a liquid crystal variable retarder(LCVR) was developed based on SLC-7607A parallel nematic liquid crystal. Its operating principle and technology was described. New method measuring retardation of the variable retarder based on Stokes parameters was put forward, and the characteristic curve describing relationship of retardation and voltage was well reproducibly drawn. Experimental result indicates that retardation is inversely proportional to the applied voltage ranging from 1V to 2.7V, and the fitted linear relation is achieved. The obtained result attributes to the development, measurement and application of LCVRs.
