Formation and Localization of Holographically Produced Interference Fringes

Theoretical and experimental studies are described on the formation and localization of holographically produced interference fringes. The fringes were shown to be localized where the correlation between the wave fields produced by the two objects identical in shape but different in the relative position attains the maximum value. A grating model of a diffusely reflecting surface was proposed, in exact agreement with the theory. Experiments were carried out to verify the discussions.
