Geometrical Aspects of Consistent Holographic Memory Design

Abstract

Based on results of diffraction theory, it is shown that the proportions of storage plate and detector matrix, respectively, page-composer, of a fast holographic mass memory are strongly coupled. A high capacity fast data store needs a large detector array. Optimized geometry results if storage plate and detector matrix have the same size. A square detector matrix, able to read about 10(10) bits in an optimum designed memory, should have a diagonal extension of about 1 m.
