Abstract
A deformable membrane assembly comprising a fluid-filled envelope, one wall of which is formed by an elastic membrane that is held around its edge by a bendable supporting ring, a support for the envelope and at least three ring-engaging members that are arranged to apply a force to the ring at spaced control points for adjusting the shape of the membrane, with the ring bending to control the shape of the membrane to a predefined form. A control point is provided at or proximate each point on the ring where the profile of the ring that is needed to produce the predefined form 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.
