Paper Abstract

Handling of optical information has become increasingly digital in nature and digital concept and techniques play an ever more dominant role. The representation of the data to be handled is of concern in the system design. Such systems consist of several units classified by their function: encoding, transmission, processing, storage, and decoding of information. Coding schemes have been introduced and developed to accommodate transducer problems between distribution of energy and material properties.Electronic devices and systems have had a significant impact on the treatment of 2- and 3-D information and have to be adapted and developed accordingly. Gradually, sophisticated computational abilities have been added together with ideas to convert 1-D modulated signals into 2-D ones. The gained additional degrees of freedom can be used to optimize the process and sampling and quantization requires refined software to filly utilize existing hardware. The flexibility to include processing of the information locally and/or globally has opened new extensions of and possibilities in, the field of synthetic counterparts of established physical methods and techniques. The spectrum of digital optical coding techniques range from sequential, pixelwise to iterative methods. Major classes of algorithms will be illustrated. Competing specific requirements, needs and tolerances will influence the choice of a suitable algorithm. Keywords: digital holography, cmputer-generated holograms, diffractive elements, hologram design
