ABSTRACT:
An optical component element which may be either used as an optical storage medium or as a component in an optical system characterized by a plurality of sub-holograms which will randomly divide a beam of coherent radiation in a plurality of partial beams with each of the sub-holograms producing a single partial beam. Each of the sub-holograms may be constructed so that the partial beam produced thereby exhibits a specific spatial configuration at specific locations in space with the spatial configurations being either focal points, focal lines, circular rings or sectors of a circle. Each of the sub-holograms may have a different area so that the partial beam formed thereby has a varying energy content. Preferably, the sub-holograms are constructed as sectors of a circle.
