ABSTRACT:
A variable focal length lens includes a plurality of layers of an electro-optic material and alternating stacked substantially transparent conductor layers and substantially transparent resistor layers. Each layer of electro-optic material is sandwiched between a separate conductor layer and a separate resistor layer. The focal length of the lens is varied by varying the voltage applied to the resistor layers.
