A METHOD OF COMPUTING A HOLOGRAM

摘要

A method of computing a hologram by determining the wavefronts at the approximate observer eye (OE) position that would be generated by a real version of an object to be reconstructed. In normal computer generated holograms, one determines the wavefronts needed to reconstruct an object; this is not done directly in the present invention. Instead, one determines the wavefronts at an observer window (OW) that would be generated by a real object located at the same position of the reconstructed object (3D-S). One can then back-transform these wavefronts to the hologram to determine how the hologram needs to be encoded to generate these wavefronts. A suitably encoded hologram (HA) can then generate a reconstruction of the three-dimensional scene (3D-S) that can be observed by placing one's eyes at the plane (OP) of the observer window (OW) and looking through the observer window (OW).
