Numerical reconstruction of digital holograms for conventional 3D display

True hologram video displays are currently under development, but are not yet available. Because of this restriction, conventional 3D displays can be used with digital holographic data. However when using conventional 3D displays, holographic data has to be processed correctly to meet the requirements of the display. A unique property of digital holograms, namely that a single hologram encodes multiple perspectives, can be used to achieve this goal. Reconstructions from digital holograms at different perspectives are processed further to meet the requirements of the conventional 3D display, which are typically based on stereoscopic images of the scene.
