摘要:
A liquid crystal adaptive lens (LCAL) includes a reference plate, a liquid crystal layer disposed in electrical communication with the reference plate, and a plurality of closed-loop electrodes disposed in electrical communication with the liquid crystal layer. The closed-loop electrodes are adapted to receive a variable control voltage such that the refractive index of at least a portion of the liquid crystal layer is adjustable such that light passing through the liquid crystal layer is capable of being redirected. By including closed-loop electrodes, the liquid crystal layer of the LCAL is capable of having a radially varying refractive index.
