Abstract

Summary from only given. To investigate the effect of data page misregistration and subsequent signal processing on the areal storage density of holographic data storage systems, we have developed a numerical simulation. A pair of 2D fast Fourier transforms simulate a 4-F optical system with a square aperture at the central shared focal plane. The detected intensity is computed by integrating over each output pixel, and the BER measured by applying the best-case intensity threshold.
