| Abstract: | Base on the observation and analysis of the super twisted nematic liquid crystal special diffraction phenomena which display in the electric field were observed and the analyzed, the differences of the interlace diffractive order in certain conditions are discovered, the relationship between liquid crystal＇s internal refractive index and the associated factor. The liquid crystal diffraction grating＇s equivalent grating constant has carried on the semi-quantitative determination in certain condition, then to establish the foundation of the liquid crystal grating＇s diffraction quantitative model. |
