Multi-plane multiplicative-noise-multiplexing holography with low crosstalk assisted by temporal multiplexing

Multi-plane holography has attracted increasing interest for reconstructing depth information. However, achieving multi-plane holography with high capacity and low crosstalk is always highly desired. Here, we proposed and demonstrated a novel multi-plane holography based on multiplicative noise multiplexing and temporal multiplexing. By utilizing the orthogonality inherent between multiplicative noise phases, the proposed holography enables the image reconstruction with simultaneous combination of multi-plane and multiplexing dimensions. The integration of temporal multiplexing contributes to further improve the signal-to-noise ratio (SNR). Both simulation and experimental results have demonstrated that, by introducing the noise engineering, this holography can enhance the information capacity and significantly lower the inter-plane and inter-channel crosstalk. This promising holography has the potential in the fields of ultrahigh-capacity 3D display, information storage, and information encryption.
