Abstract:

Theory and experiments in the area of computer-generated holograms for geometric transformations are presented. Geometric transform holograms are divided into two categories 1 those which have a continuous fringe structure, and 2 those which consists of a set of discrete subholograms. Criteria for the realizability of a continuous geometric transform hologram are described. Examples of both types of hologram are developed to map rings of different radii to a linear sequence of points. They allow the replacement of a ring detector by a linear detector array without loss of signal energy and can be applied to optical spectrum analysis and angle-wavelength multiplexing for data transmission through optical fibers. Originator-supplied keywords include Holograms, Geometric Transformations, and Computer-Generated Holograms. Author
