摘要： Disclosed is a multiplexing method and apparatus that allows holograms to be spatially multiplexed with partial spatial overlap between neighboring stacks of holograms. Each individual stack can additionally take full advantage of an alternate multiplexing scheme such as angle, wavelength, phase code, peristrophic, or fractal multiplexing, for example. An amount equal to the beam waist of the signal beam writing a hologram separates individual stacks of holograms. Upon reconstruction, a hologram and its neighbors will all be readout simultaneously. An filter is placed at the beam waist of the reconstructed data such that the neighbors that are read out are not transmitted to the camera plane. Alternatively, these unwanted reconstructions can be filtered out with an angular filter at an intermediate plane in the optical system that has a limited angular passband.

摘要： The invention relates to a holographic display device for representing a two-dimensional and/or three-dimensional scene. The holographic display device comprises at least one spatial light modulator device and an optical component. The at least one spatial light modulator device is provided in order to reconstruct the scene and in order to generate at least one virtual visibility region in an observer plane. The optical component is configured with at least two regions that have a different transparency to one another, the value of the transparency respectively lying between 0 and 1. Furthermore, the optical component is arranged in the display device in such a way that it provides filtering, to be carried out at least partially, of a diffraction order spot in at least one diffraction order inside the virtual visibility region.
