Abstract

See full text

An actuation mechanism for simultaneous actuation of first and second variable focal length lenses is disclosed. Each lens comprises a distensible membrane bounding a fluid-filled cavity, the focal length varying with the degree of curvature of the membrane as it distends. The actuation mechanism comprises a hydraulic master actuator in fluid communication with a hydraulic slave actuator associated with the first lens and with a hydraulic slave actuator associated with the second lens. Each slave actuator is configured to vary the degree of distension of the membrane of its associated lens in response to operation of the master actuator, whereby the master actuator is operable to cause a variation of the degree of distension of the membranes of both the first and second lenses simultaneously.
