Paper Abstract

We propose a high-speed optical measurement method for determining cell parameters such as cell thicknesses and twist angles of reflective liquid crystal (LC) cells. A polarization-converting device prepared using a circularly-homogeneously aligned LC (CH-LC) cell and a charge couple device (CCD) camera are used. The spatial light intensity distribution from the reflective LC cell through the CH-LC cell and the local minimum point are measured. Then the cell parameters can be derived by using the coordinate values of the point and the Jones matrix analysis.
