HOLOGRAPHISCHES VERFAHREN ZUM SPEICHERN UND AUSWAEHLEN VON DATENSAETZEN

摘要

The associative holographic store has the data sets stored as coded point rasters in addressable individual holograms. The addressed individual holograms can be read via an integrated transducer providing a corresponding charge distribution pattern. The resulting charge distribution patterns for successive read-out operations are additively superimposed, with each point of the transducer corresponding to a key word, so that the charge for each point of the superimposed patterns signifies the relevance of the key word to the stored data. Pref. the light energy during read-out can be controlled in dependence on the weighting factors of the stored data.
