US 10,371,871 B2 · Optical device for stabilization of images

Abstract

An optical device for the stabilization of images, including a first deformable membrane and a second deformable membranes, a support to which a respective peripheral anchoring area of each of said membranes is connected, and a constant volume of fluid enclosed between the first and the second membrane, said fluid producing mechanical coupling of said first and second membranes. The optical device also includes: a first actuation device of a region of the first membrane located between the peripheral anchoring area and a central part of the first membrane; and a second actuation device of a region of the second membrane located between the peripheral anchoring area and a central part of the second membrane. A control means of the first and second actuation devices is configured, from a rest position where the first and second actuation devices are inactive, to have multiple operating modes to apply respective actuation voltage to the first actuation device or the second actuation device.

An optical device, comprising:

a first deformable membrane;
a second deformable membrane;
a support to which a respective peripheral anchoring area of each of the first deformable membrane and the second deformable membrane is connected;
fluid enclosed between the first deformable membrane and the second deformable membrane;
a first actuation device and a second actuation device, each comprising:
a respective first actuator arranged in a first part of an actuation region of a respective one of the first deformable membrane or the second deformable membrane, wherein the actuation region is located between the respective peripheral anchoring area and a respective central part of the respective deformable membrane;
a respective second actuator arranged in a second part of the actuation region of the respective deformable membrane, wherein the second part is diametrically opposed to the first part;
wherein at least one of the first actuation device or the second actuation device is configured to deform, via at least one of the respective first actuator or the respective second actuator, the respective deformable membrane such that the respective central part of the respective deformable membrane is shaped to deviate a path of light incident on the central part to stabilize an image.
