| 摘 要： | <正>A 128×128 elements cylindrical liquid crystal(LC) lens array with electrically controllable focal length is proposed.The cylindrical LC lens array uses transparent indium tin oxide(ITO) films as electrode,avoiding to affect the optical path operating in the voltage-off status.As the top electrode of the cylindrical LC lens array contacts with LC,the operation voltage root-mean-square(RMS) amplitude can be as low as 1.4 V and the response time is about 20-30 ms.The special optical focusing feature of the cylindrical LC lens array is got.And the focal length of this array is about 60-450μm.
