A holographic display system for generating a super hologram with full parallax in different fields of view in the horizontal and vertical directions. The display system includes assemblies or subsystems each adapted to combine holographic displays and coarse integral displays to produce or display a coarse integral hologram. Briefly, the display system described herein teaches techniques for enhancing operations of coarse integral holographic (CIH) displays. The enhanced CIH displays may utilize ganged scanners, may operate scanners to provide boustrophedon scanning, may be configured to add color information such by view sequential color hologram display and scanning, may replace or supplement X-Y scanning abilities with a resonant scanner, and may replace physical lenslet arrays by generating and displaying a holographic lenslet for each elemental hologram used to create the super hologram.

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.
