Abstract

The present invention relates to an actuator for moving a rigid element, e.g. an optical element such as mirror, the element being mechanically coupled to a frame with a bendable coupling, wherein actuator elements are mounted on said coupling between the frame and element, the coupling and actuator elements being adapted to provide a movement to the element when subject to signal from a signal generator.
