Abstract
An optical device with focal length variation including a first deformable membrane, a second deformable membrane, and a support to which a respective peripheral anchoring area of each of said membranes is connected. A constant volume of fluid is enclosed between the first and the second membrane, said fluid producing mechanical coupling of said first and second membranes. An actuation device of a region of the first membrane located between the anchoring area and a central part of the first membrane, configured to deform by application of electrical actuation voltage in a single direction of deflection to displace at least a portion of the fluid volume, said displacement of fluid being likely to cause deformation of the central part of the first membrane based on application of an electrical actuation voltage to the actuation device.
