Abstract

Foreliggende oppfinnelse angår en fremgangsmåte for parallell optisk dekoding av et digitalt fasebilde til et intensitetsbilde ved algoritmisk koding av en dataside i fasebildet og parallell optisk dekoding ved å fange interferensen til fasedatasiden og dens kopi skiftet med en eller noen få piksler med hensyn til hverandre.
