Patent ID: 8395833

Claim:
Holographic projection system having a display screen and at least one holographic projector which comprises both spatial light modulator means which modulate a wave for the reconstruction of a scene with holographic information of video holograms and projection means, with which a position controller adjusts a direction of propagation of the modulated wave and an exit position in order to direct the modulated wave through the display screen at a desired eye position, and to track the modulated wave with the reconstructed scene to the desired eye position, wherein the holographic projection system comprises a system controller which: discretely activates a sequence of modulator segments in the light modulator means, wherein a modulator segment comprises portions of modulator cells to provide individual modulated partial waves in a time multiplex, and which adjusts with the help of the position controller a direction of propagation which depends on the active modulator segment, and a corresponding exit position of the modulated partial wave such that each active modulator segment directs its modulated partial wave with a reconstructed segment of the scene through a corresponding screen segment on the display screen at a current eye position, where all reconstructed modulated partial waves together render the entire reconstructed scene visible.
