Computer-Generated Hologram Based on Reference Light Multiplexing for Holographic Display

In this article, we propose a reference light wave multiplexing scheme to increase the information capacity of computer-generated holograms. The holograms were generated by different waves and superimposed together as multiplexed hologram. A modified Gerchberg–Saxton algorithm was used improve image quality, images could be reconstructed when hologram illuminated corresponding waves. We performed both numerical simulations optical experiments demonstrate feasibility proposed scheme. Numerical showed that method reconstruct multiple successfully single are consistently good with simulations. It is expected has great potential widely applied in holographic displays future.
