摘要
Algorithms for improved and more efficient rendering of three-dimensional images for use with holographic display systems. These algorithms include creating layers orthogonal to a viewing direction, the separate layers representing different depths in the image. The layers are created based on knowing the color and depth of each point in the image. Each layer then goes through an FFT process until the information for each layer is represented as a diffraction pattern. A holographic lens is then applied to the diffraction pattern of each layer. This lens will cause that layer to appear, in a hologram based thereon, at a different depth than the other layers. The layers, each with their separate lenses, are then coherently summed up and when applied to a suitable portion of a holographic display system (e.g., an SLM), a hologram can be created for that view. A tiled array of such holograms can be combined together by the holographic display system.
