    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 (34) having a resistive bridge (38) located between adjacent electrodes, and in a preferred embodiment, input connections (70) 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.

    摘要翻译： 包括液晶的电光透镜，其中可以通过施加电场来改变透镜的功率。 在一个实施例中，基于液晶的透镜包括具有位于相邻电极之间的电阻桥（38）的环形电极（34），并且在优选实施例中，用于若干电极环的输入连接（70）在透镜上间隔开。 在另一实施例中，提供了通过使用相位复位来增加光功率的液晶型透镜，其中在一个实施例中，透镜在液晶单元的相对侧上包括在基板的表面上的环形电极，使得 固定相位可以被添加到允许跨每组电极相位相同且也相对于先前组匹配的每组电极。
