Abstract
A radiation dispersing cavity has its interior surface covered by a plurality of deformations, each of which acts as a dispersing element which is small with respect to the effective diameter of the cavity and yet large with respect to the wavelengths processed by the integrating cavity. The interior surface of the cavity is coated with a material which provides the proper reflectivity for the wavelengths of interest. The interior of the cavity is covered with at least two different sets of interlocking deformations producing at least two different apparent planes of reflection. Use of alternating concave-inward, concave-outward deformations facilitates smooth transitions between deformations, preventing development of hot spots at sharp discontinuities.
