Abstract
Techniques for generating 3-D holographic images of a 3-D real or synthetic object scene are presented. A holographic generator component (HGC) can obtain a real or synthetic 3-D object scene. The HGC generates a high-resolution grating, and generates a low-resolution mask based on the 3-D object scene. The HGC overlays the mask on the grating to generate the hologram, which can be a digital mask programmable hologram. The HGC can use the grating as an encryption key, if desired, wherein the mask can be encrypted based on the encryption key. The display component receives the hologram and can generate holographic images, based on the hologram, and display the holographic images using one or more low-resolution displays. The grating and display can be arranged in various formations in relation to each other. A single display can be partitioned into a tile structure for displaying holographic images in the respective tiles.
