摘要
Electro-optic lenses, including liquid crystals, wherein the power of the lenses can be modified by application of an electric field. In one embodiment, the liquid crystal-based lenses include ring electrodes having a resistive bridge located between adjacent electrodes, and in a preferred embodiment, input connections for several electrode rings are spaced on the lens. In a further embodiment, liquid crystal-based lenses are provided that can increase optical power through the use of phase resets, wherein in one embodiment, a lens includes ring electrodes on surfaces of the substrates on opposite sides of the liquid crystal cell such that a fixed phase term can be added to each set of electrodes that allows for phase change across each group of electrodes to be the same and also be matched with respect to a previous group.
