摘要：

A liquid crystal lens with focus movable off as well as along the axis is realized. There are two electrodes in the cell: one with a hole, and another with resistance and subelectrodes. The focus can be adjusted along the axis by the applied voltage across the two electrodes, just as that in a conventional liquid crystal lens, and it can also be moved off the axis by the voltage across the subelectrodes. Electrical control of the movements of the focus in the two directions is demonstrated in the paper. (C) 2003 Elsevier B.V. All rights reserved.
