Abstract
An optical device has a deformable membrane and a support to which a peripheral anchoring area of said membrane is connected. The optical device further includes a cavity filled with a constant volume of fluid, the cavity being delimited by the membrane, a base extending substantially parallel to the membrane and a wall of the support extending between the base and the membrane. The optical device further includes an actuation device of an area of the membrane located between the peripheral anchoring area and a central part of the membrane, configured to bend by application of electrical actuation voltage so as to move some of the volume of fluid located in a flow region located between the actuation area of the membrane and the base of the cavity. The optical device also includes a heating element adapted to locally heat the fluid in the flow region.
