Popis: We propose a measurement method to determine the cell parameters which are a cell gap thickness, a twist angle and dispersion for a twisted-nematic liquid crystal cell by the spectral method. This method finds the variation point of transmission with respect to the wavelength λ. The proposed method can be applied to the determination of cell thickness and twist angle in the low cell gap as well as to the high cell gap.
