Abstract
A deformable lens structure includes: a deformable first layer having a first outer surface adapted to receive an incident light beam, and a first inner surface opposite the first outer surface; at least a first central portion of the first layer being transparent to the light beam; a second layer having a second inner surface facing the first inner surface and a second outer surface opposite the second inner surface, at least a second central portion of the second layer being transparent to the light beam; a shaped spacer element positioned between the first inner surface and the second inner surface, and an inner chamber containing a liquid transparent to the light beam; first and second electrostatic actuators operatively associated with the first layer and second layers and positioned at the first central portion of the first layer and at the second central portion of the second layer, respectively.
