摘　　要：液晶的一个重要特性是：液晶的折射率会随所加于液晶上的电压的变化而变化。利用这一特性，我们就有可能制作焦距可变的液晶透镜，变焦液晶透镜对于解决老年人因老花而需佩戴多副眼镜的问题具有重要意义。研制这种变焦透镜的前提，首先要掌握液晶折射率随所加电压变化的规律。本文正是对这一规律进行了研究实验，并得出了实验结果。One of the most important properties of liquid crystals is that their refractive index could be changed by applying a relatively low potential across them.Using this property,it is possible to make a variable focus liquid crystal lens which may be very useful for old people who have to wear double focus glasses or more than two pairs of glasses because presbyopia.In order to develop this kind of variable focus lens,the continuous change of the refractive index of liquid crystal by the voltage applied to the crystal should be investigated.The results of investigation for some liquid crystals are presented in this paper.
