报道了一种双电压驱动的液晶透镜。该透镜具有可电调谐的焦距。可变聚焦能力的范围非常宽，覆盖约0.8- 10.7D。在整个焦距范围内，LC透镜保持高光学质量。可以以简单的方式驱动LC透镜以防止向错线的出现。演示了液晶透镜在成像中的应用。(C)2004年美国光学学会。
A liquid-crystal (LC) lens driven by two voltages is reported. The lens has a focal length that is electrically tunable. The range of the variable focusing power is very wide, covering approximately 0.8-10.7 D. In the entire focal range the LC lens maintains high optical quality. The LC lens can be driven in a simple way to prevent the occurrence of a disclination line. The use of the LC lens in image formation is demonstrated. (C) 2004 Optical Society of America.
