Abstract
An actuator may be integrated into an optical element such as a liquid lens and configured to create spherical curvature as well as a variable cylinder radius and axis in a surface of the optical element. An example actuator may include a stack of electromechanical layers, and electrodes configured to apply an electric field independently across each of the electromechanical layers. Within the stack, an orientation of neighboring electromechanical layers may differ, e.g., stepwise, by at least approximately 10°.
