| Popis: | Using the optical guided wave method,the full leaky waveguide mode assembled by prism,matching fluid of refractivity and twisted nematic liquid crystal cell is studied under different voltages.Some experimental data of reflected light corresponding to different external angles through the full leaky guided mode of twisted nematic liquid crystal are obtained.From Snell law,some experimental curves between the reflectivity and the internal angle are also obtained.By comparing these experimental curves with the theoretical curves obtained from multi-layer optics theory,with a greatly good accordance,the director profile of twisted nematic liquid crystal cell for different voltages is determined. |
