Abstract
An embodiment of a method of designing a grooved reflector comprises selecting two given wavefronts; and designing two surfaces meeting at an edge to form a groove such that the rays of each of the given wavefront become rays of a respective one of the given wavefronts after a reflection at each of the surfaces. Multiple grooves may be combined to form a mirror covering a desired area. A mirror may be manufactured according to the design.
