Optical design of holographic gratings
Since the invention of the hologram, lens designers have considered this intriguing device for various applications, particularly designs for laser systems. Holographic optical elements (HOEs) may be made directly by computer generation or by optical construction methods. Computer generation is in some senses ideal because the designer has complete control of the hologram grating lines. Computer generation of holograms is of interest primarily for surface holograms rather than volume holograms and is at present restricted to relatively small diameter devices on flat surfaces.
