Maximum information capacity of a three-dimensional hologram

This Letter is devoted to the problem of the maximum information capacity of a three-dimensional hologram with optimal utilization of the dynamic range of the storage medium. A hologram is treated as an object of information theory. Diffraction-limited holographic writing is analyzed on the basis of the reciprocal-lattice formalism. The calculation of the information capacity of the three-dimensional hologram is reduced to analysis of a set of multiplexed holograms each of which possesses a finite signal/noise ratio determined by the dynamic range of the holographic medium. The optimal number of pages which give the maximum information capacity with angular multiplexing is found.
