Abstract
An optical device includes a soft polymer film having a first and second surface. A first compliant electrode is connected to the first surface and a second compliant electrode is connected to the second surface. A rigid optical element is connected on the first and/or second surface or integrated into the polymer film.
Claims15
An optical device comprising:
- a polymer film arranged in a plane and comprising a first surface and a second surface, wherein the plane of said polymer film comprises first and second non-overlapping sections,
- a first electrode located on said first surface and arranged in said first section,
- a second electrode located on said second surface and arranged in said first section,
- a rigid, undeformable optical element connected to said polymer film and arranged in said second section, wherein the application of a voltage difference between said first and said second electrodes displaces said optical element parallel to the plane of said polymer film,
- wherein said electrodes are arranged at a first side of said optical element but not on a second, opposite side of said optical element.

A method for operating an optical device, wherein said optical device comprises
- a polymer film comprising first and second non-overlapping sections, lying in a plane, and having a first surface and a second surface,
- a first electrode located on said first surface and arranged in said first section,
- a second electrode located on said second surface and arranged in said first section, and
- a rigid, undeformable optical element connected to said polymer film and arranged in said second section, wherein said method comprises the step of applying a voltage difference between said first electrode and said second electrode, thereby displacing said rigid optical element substantially along a plane parallel to said polymer film,
- wherein, for scrambling a light beam, said light beam is sent through or reflected by said optical element, wherein said optical element has a curved surface and is being oscillated in an oscillating motion, and wherein said optical element has a purely convex or a purely concave surface in the area contacted by said light beam.
