| description | An optical device with variable aperture, including a deformable membrane having a central optical area, a support to which a peripheral anchoring area of said membrane is connected, a first cavity filled with a constant volume of a first transparent fluid in a determined range of wavelengths, said cavity being delimited at least in part by a first face of said membrane and a wall of the support. The optical device also includes at least one actuation device of a region of the membrane located between the peripheral anchoring area and the central optical area of the membrane, configured to bend said region of the membrane by application of electrical actuation voltage so as to displace some of the volume of the first fluid towards the center or towards the periphery of the first cavity, said displacement of fluid being intended to deform the central area of the membrane. |
