Paper Abstract

A 4-focal length, telocentric holographic storage system architecture usually employs an aperture stop. The aperture plays an important role in determining the areal density of storage as well as the extent of inter-symbol interference. We propose a figure-of-merit for such an aperture. For simplicity, we assume that a zero-forcing equalizer is used to compensate for inter-symbol interference caused by the point spread function.
