摘要： A variable-power lens comprises first and second lens elements one behind the other along an optical axis of the lens. Each element has opposed planar and curved surfaces such that the thickness of each element in a direction parallel to the optical axis varies in a direction transverse to the optical axis. The elements are relatively moveable in the transverse direction, whereby the power of the lens may be varied. The elements are arranged such that the curved surface of the first element is adjacent the second element and the planar surface of the first element bears a diffractive pattern.

摘要： 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.

摘要： The present invention provides a deformable membrane assembly 1 comprising an elastic membrane 8 that is held under tension around its edge by a bendable membrane supporting member 2,10, a body of fluid in contact with one face of the membrane, the pressure of the fluid being controllable for adjusting the shape of the membrane, and one or more bending controllers 24 acting on the supporting member 2, 10 to control the bending of the supporting member in response to loading through tension in the membrane. The bending stiffness of the membrane-supporting member 2, 10 varies round its extent to control the profile of the edge of the membrane 8; etc. upon actuation. A variety of different types of bending controllers are disclosed which permit out-of-plane bending of the supporting member 2, 10 but prevent or control in-plane bending or deformation of the supporting member. In some embodiments, the bending controllers permit a degree of controlled in-plane bending of the supporting member 2, 10 in order to control the strain in the membrane 8 upon actuation.
