| 摘 要： | 本文解释了液晶膜中人射光强(I_)对透射光强(I_)曲线的振荡现象,并由观测到的振荡周期估算了液晶分子重取向引起折射率的变化,理论与实验结果符合,讨论了I_对I_曲线在临界场处透射率突变的机理。

| Abstract: | The oscillation phenomenon of incident light intensity Iin vers transmission intensity Iout curve in nematic liquid crystal layer has been explained theoretically. The change of refractive index due to molecular reorientation has been estimated by using the observed oscillatory period. Theoretical result is in agreement with that of experiment. A sudden change of absorption coefficient of nematic liquid crystal layer due to molecular reorientation has been proposed and discussed. |
