Numerical simulations on 3D shift multiplexed self-referential holographic data storage: Shift multiplexing properties along z-axis

The 3D shift multiplexing method for high-density self-referential holographic data storage is proposed. As the fundamental evaluations of the proposed method, we focus on the multiplexing properties along the z-axis. Concretely, we demonstrate the z-shift multiplexing of 25 datapages after clarifying the shift selectivity along the z-axis.
