ABSTRACT:
A structure for responding to incident radiation for directing said radiation in a selected direction with respect to the structure, the structure using at least two outer diffraction elements and an intermediate diffraction element, the diffraction characteristics being selected so that the selected direction remains within relatively limited confines independent of the angles of incidence of the incoming radiation over a selected range thereof.
