摘要： An adaptive lens comprises an actuator and a lens, the lens being mechanically coupled to the actuator so that energization of the actuator adjusts a focal point of the lens. The actuator may comprise a multilayer stack of electromechanical polymer (EMP) layers, having electrodes configured to apply an electric field across each EMP layer. The actuator may be operable to move and/or deform a lens, so as to adjust the focus properties of the lens. In some examples, the actuator has an annular shape, supporting a lens within the inner radius of the annulus. The lens position may be adjusted in an axial direction. In other examples, the actuator may be mechanically coupled a surface of a deformable lens, either directly or through another element of a lens structure. A strain applied to the lens modifies a curved surface of the lens, hence modifying the focal length of the lens.
