An important feature of computer generated holograms (CGHs) is to create wavefronts that may be defined only mathematically. Since A. W. Lohmann and his colleagues invented CGHs in 1966 for spatial filtering in image processing, the applications of CGHs have multiplied to include 3-D display, optical testing, diffractive/binary optics, bifocal intraocular lenses, wavefront transformations for material processing, pickup heads for optical disks, focal plane array detection, coherent laser addition, beam steering, and optical interconnects for parallel computing and neural computing. Today, the applications of CGHs continue to expand. This book features a selection of papers that examine different aspects of the development of CGHs from the 1960s through 1990, because there is no substitute for reading the original papers on any subject, even if that subject is mature enough to have many single-aspect monographs and textbooks. It is hoped that this selection of papers will be valuable additions to many working libraries on this expanding, expansive subject.

Laser Beam Mode Selection by Computer Generated Holograms brings attention to a new class of optical elements called modans, with applications in laser and fiber optics. Separation of the transverse modes by modans is discussed in close analogy to well-known effects of color separation by diffraction gratings. The book describes the basic questions of digital holography in the recording of complex wavefronts on phase-only media, binary coding cells, multilevel computer-generated holograms, quantization and sampling, image reconstruction, and computer generation of multifocal and multibeam holograms. This collective effort summarizes 12 years of scientific activities in the development of diffractive optical elements and provides considerable material never before published. An interesting appendix dedicates itself to mathematical proof of optimal properties of orthogonal base-functions and eigenfunctions.
