Multifunctional meta surface holograms that can produce multiple holographic images, are key flat optical devices for real life ultra compact holographic display application. To generate a multiplex metal hologram, we use a straightforward approac

We present a protocol for fabrication of spin- and direction-multiplexed visible metaholograms, then conduct an optical experiment to verify their function. These metaholograms can easily visualize encoded information, so they can be used for projective volumetric display and information encryption.
