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.
An optical assembly comprising:
An optical assembly comprising a plurality of metamirrors, where each metamirror includes a substrate, a reflective layer formed to the substrate, where the reflective layer is a separate layer from the substrate, an array of optical metaelements extending from the reflective layer and an actuator assembly having an array of micro-actuators coupled to the substrate opposite to the reflective layer, said micro-actuators being controlled to control the orientation and bending of the metamirrors to control how a combination of the metaelements focus a light beam that is reflected off of the reflective layers.
A metamirror comprising a substrate, a reflective layer formed to one side of the substrate, where the reflective layer is a separate layer from the substrate, an array of optical metaelements formed to a side of the reflective layer opposite to the substrate and an actuator coupled to a side of the substrate opposite to the reflective layer, said metaelements combining to focus a light beam that is reflected off of the reflective layer to a focal point and said actuator being controlled to control the orientation and bending of the metamirror to control how the metaelements focus the light beam.
