Solar mirror, Binary actuation, Active optics, Tracking
Thermal solar energy collectors
The invention provides a new approach to correct manufacturing imperfections and shape deformations for solar concentrators. In this approach, binary actuators are embedded in a compliant mirror substructure. Actuators are deployed in a specified pattern to correct the mirror shape. The precision of the binary actuated system is determined by location and number of actuators. As the number of actuators in a system increases, the precision of the device approaches a conventional continuous system.
