摘要： A deformable membrane assembly comprising a fixed support, a fluid-filled envelope, one wall of which is formed by an elastic membrane that is held under tension around its edge by a flexible membrane supporting member, the supporting member being coupled to the fixed support at a plurality of discrete control points around the supporting member by engaging members for controlling the position of the membrane edge; and an adjuster for adjusting the pressure of the fluid within the envelope to adjust the shape of the membrane; wherein at least three control points are provided that are situated around the membrane edge at spaced locations selected to increase the energy of the lowest order out-of-plane bending mode of the supporting member while allowing the membrane to deform according to one or more selected Zernike polynomials. An article of eyewear comprising such a deformable membrane assembly is also disclosed.

摘要： A membrane assembly 150 for a variable focusing power optical assembly 100 is disclosed. The membrane assembly 150 comprises a distensible membrane 155 that is held under tension around its periphery (boundary B) by at least one bendable support ring 159 and one or more bending actuators 170, each comprising a selectively operable self-bending strip, which are attached contiguously to respective discrete sections of the support ring 159 for actively controlling the curvature of those sections of the support ring 159. Also disclosed is a variable focusing power optical assembly 100 comprising such a membrane assembly 150. Further disclosed is an article of eyewear 80 comprising at least one such variable focusing power optical assembly 801.

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： A deformable membrane assembly comprises an at least partially flexible fluid-filled envelope, one wall of which is formed by an elastic membrane that is held around its edge by a resiliently bendable supporting ring, a fixed support for the envelope and selectively operable means for causing relative movement between the supporting ring and the support for adjusting the pressure of the fluid in the envelope, thereby to cause the membrane to deform. The bending stiffness of the ring varies round the ring such that upon deformation of the membrane the ring bends variably to control the shape of the membrane to a predefined form. The moving means comprise a plurality of ring-engaging members that are arranged to apply a force to the ring at spaced control points. There are at least three control points, and there is a control point at or proximate each point on the ring where the profile of the ring that is needed to produce the predefined form upon deformation of the membrane exhibits a turning point in the direction of the force applied at the control point between two adjacent points where the profile of the ring exhibits an inflection point or a turning point in the opposite direction.

摘要： A membrane assembly (150) for a variable focusing power optical assembly (100) comprising a distensible membrane (155) that is held under tension around its periphery by at least one bendable support ring (159) and one or more curvature controllers (170) that are mounted to respective discrete sections of the support ring (159) for actively controlling the curvature of those sections of the ring in a plane (Btz) that is parallel to a z-axis normal to an (x,y) plane which is defined by the un-deformed support ring and tangential (t) to the periphery (boundary B) of the membrane. Also disclosed is a variable focusing power optical assembly (100) comprising such a membrane assembly, which has a compressible fluid-filled envelope having a first wall formed by the distensible membrane (155), an inflexible second wall (114) opposite the first wall, the support ring (159) being held at a fixed distance from the second wall at hinge points that are spaced apart around the support ring (159) and being bendable towards or away from the second wall intermediate the hinge points on the z-axis which is substantially aligned or coincident with an optical axis of the optical assembly (100), and a side wall (146) between the first and second walls that is collapsible to accommodate such bending; wherein the membrane (155) is arranged to distend in a direction towards or away from the second wall upon bending of the support ring (159) between the hinge points. In some embodiments, the second wall (114) may be formed by or supported on a surface (114) of a rigid body (110), and the support ring 159 may be mounted on the rigid body (110) by support pins (130) at the hinge points. Also disclosed is an augmented reality headset or helmet (80) comprising an augmented reality display module (800) comprising two such variable focusing power optical assemblies (801, 901) arrange one in front of the other in optical alignment with a waveguide display (1001) interposed therebetween.
