研究了柱状孔中含有液晶的阳极氧化铝膜的透光率。由于液晶被封闭在直径为1000 A的窄孔中，因此不仅由于液晶和氧化铝之间的折射率失配，而且由于液晶内部的折射率的显著分布，发生光散射。透射率随电场和温度可逆地变化。
The optical transmittances of anodic alumina films which contain nematic liquid crystals in columnar pores were studied. Since liquid crystals are enclosed in narrow pores of ∼2000 A diameter, light scattering occurs not only by the refractive index mismatch between the liquid crystals and alumina but also by the prominent distribution of the refractive index inside the liquid crystals. The transmittance changes reversibly with an electric field and temperature.
