Holographic apparatus and method

摘要

The invention relates to a method of and apparatus for displaying a holographically generated video image having plural video frames. For each frame there is provided and computed ( 20 ) a respective sequential plurality of holograms. Each said sequential plurality of holograms of the plural video frames are sequentially displayed on a diffractive element (12) for viewing the replay field thereof, and the noise variance of each frame is perceived as attenuated by averaging across said plurality of holograms.
