Abstract
A method for designing microstructures for a light shaping reflector for use in a light field display is provided. A mathematical function is derived to reflect light uniformly from an incident light beam. Curved elements shaped by the mathematical function are combined to design the microstructures. The microstructures are formed in a reflective surface to provide the light shaping reflector for use in the light field display.
