An optical assembly including a plurality of metamirrors, where each metamirror includes a substrate, a reflective layer formed to the substrate, an array of optical metaelements extending from the reflective layer and an array of micro-actuators coupled to the substrate opposite to the reflective layer. The combination of the micro-actuators are controlled to control the orientation and bending of the metamirrors to set how the metaelements focus a light beam that is reflected off of the reflective layers.

Actively deformable metamirror

A multichannel, surface parallel, zonal transducer system includes a membrane and a compound transducer mounted on the membrane, the compound transducer including a plurality of transducer elements extending generally parallel to the membrane, interconnected in a closed network and individually addressable.

Multichannel, surface parallel, zonal transducer system

Fabricating a deformable mirror by providing a plurality of actuators and a support structure supporting and at least partially surrounding the actuators; applying an optical membrane across the actuators and at least a portion of the support structure; the optical membrane including a first area, a second area and an intermediate area elastically decoupling the first and second areas; bonding the first area to the actuators and the second area to the support structure; and polishing the optical membrane.

Edge constrained optical membrane deformable mirror and method of fabricating

An actuator for a deformable optical component includes a stack of ferroelectric layers, a plurality of electrodes for applying a voltage across each layer; every other electrode extending to an associated first conductor path and interstitial electrodes extending to an associated second conductor path the first conductor path or receiving a first conductor lead, the second conductor path for receiving a second conductor lead to contact the respective electrodes.

An integrated wavefront correction module including a mounting device a deformable mirror carried by the mounting device for correcting for high spatial and temporal frequency error in an incident wavefront and a tip-tilt correction mechanism including a base and a plurality of tip-tilt actuators interconnected between the base and one of the flexible and fixed portions and a plurality of support posts interconnected between the base and the other of the flexible and fixed portions or alternatively the tip-tilt correction mechanism may include at least one actuator platform, a base, a first set of tip-tilt actuators for adjustably supporting the at least one actuator platform from the base and a second set of tip-tilt actuators for adjustably supporting the mounting device from the at least one actuator platform for adjusting the mounting device and the deformable mirror together to compensate for tip-tilt errors in the incident wavefront with the tip-tilt actuators being operated typically at mid-range in order to define a center of rotation at the mirror surface.
