Abstract

Analytical shift selectivity equations assume an infinite hologram size. When developing a compact holographic storage system, one uses small holograms. From a practical viewpoint, it is better to use reflection type discs, in which the entire optical system, writing and reading objectives, among others, are on the same side of the disc. For reflection-type holographic discs, it is important to use half-cone-shaped reference beams to avoid generating ghost images caused by phase conjugate readout. Our calculations show significant discrepancy between the shift selectivity curves corresponding to the approximated analytic equation and the numerically calculated shift selectivity curves.
