Abstract:
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.
