Proposed a new method of determining the cell thickness and the twist angle of twisted nematic liquid crystal cells
a quarter-wave plate was inserted between the liquid crystal cell and the analyzer
a stepper motor rotated the Retarder by 360
and measured the light intensity of every modulated point
solved the stokes parameters of polarization light exiting from the liquid crystal cell using Fourier analysis method
thereby determining the cell thickness and the twist angle. Experiments indicated that it is suitable for measuring the low-cell-gap accurately. In addition
it also can be applied to the measurement of the cell thickness and twist angle of single polarizer reflected liquid crystal cell.
