Abstract:
A liquid crystal adaptive lens (LCAL) comprising:a reference plate; a liquid crystal layer disposed in electrical communication with said reference plate; a plurality of closed-loop electrodes disposed in electrical communication with said liquid crystal layer, said plurality of closed-loop electrodes adapted to receive a variable control voltage such that a refractive index of at least a portion of said liquid crystal layer is adjustable such that light passing through said liquid crystal layer is capable of being redirected; at least one pair of conductors in electrical contact with at least two closed-loop electrodes; and at least one connector electrically connecting at least two closed-loop electrodes and each conductor of a respective pair of conductors, wherein said at least one pair of conductors and said at least one connector are capable of providing the variable control voltage to said plurality of closed-loop electrodes.
