Abstract:
1. Digital signal processing device for computing computer-generated video holograms with digital slicer means, which assigns object data defining objects in a three dimensional scene to a number of virtual section layers, each virtual section layer defining a separate object data set, such that a video hologram data set for a video hologram is calculated from some or all of these object data sets, containing: (a) first transformation means for computing from each object data set a separate, two-dimensional wave field distribution for a virtual observer window near which an observer's eye is located in a reference layer situated at a finite distance from a video hologram layer, and buffer memory means for buffering transformed object data sets, (b) adding means for adding the transformed object data set of all virtual section layers to generate a wave field expression of an aggregated observer window data set, and (c) second transformation means for transforming the aggregated observer window data set from the reference layer to the video hologram layer situated at a finite distance and parallel to the reference layer, to generate the video hologram data set for an aggregated video hologram.
