| 摘 要： | 基于常开型液晶光阀的电光特性设计了一种司机夜间行车时佩戴的液晶眼镜．液晶眼镜能够主动根据外界光强变化改变自身的透射率,从而使透射光强趋于稳定值．实验结果表明液晶眼镜能有效防止对面车灯引起的眩目, 同时不影响司机对路面的观察．

| Abstract: | A kind of liquid crystal glasses for drivers at night is designed. It is based on electric-optic effect of liquid crystal light valves. This kind of glasses can adjust the transmissivity according to the light intensity. Thus the transmitted intensity remains steady. The experiments show that dazzling caused by opposite light can be avoided effectively, and the lines of sight of drivers could not be influenced. |
