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.

摘要： A three-dimensional imaging system based on a stereo hologram is disclosed. Images composed of sub-images having the same vertical-horizontal resolutions which are generated at plural image projection modules having a two-dimensional arrangement structure are projected to a prism array plate or a transmission-type diffusion plate, and are converted into light points, i.e., image points through a microlens array unit. A diffusion plate used as an image display screen is mounted to a position at which images diffused from the light points intersect with images diffused from the adjacent light points.

摘要： The present invention relates to a light modulator device with a spatial light modulator, a structured polariser means, a controllable polarisation means and a light wave multiplexing means. The spatial light modulator comprises discretely addressable modulator cells. Two modulator cells each are combined to form a modulation element. The modulator cells modulate light waves which are capable of generating interference of a propagating light wave field with holographic information in a spatially structured way such that a specifiable spatial distribution of object light points of a three-dimensional scene is holographically reconstructed. The modulator cells of each modulation element are adjacently arranged regarding the direction of propagation of the light wave field. The light which is modulated by adjacently arranged modulator cells is given different polarisation states by the structured polarizer means.
