Method for generating computer-generated video holograms in real time by means of propagation

摘要

The invention relates to a method for generating video holograms in real time for a holographic reproduction device using at least one light modulator means in which a scene split into object points is encoded as a whole hologram in the form of the reconstruction of a visibility region in a periodicity interval of the reconstruction of the video hologram. The reconstruction of an individual object point only requires part of the whole hologram encoded on the light modulator means. The invention is characterized in that, for each object point, the contributions for propagation of the light waves in the visibility region can be determined from at least one look-up table.
