Patent ID: 8358454

Claim:
Holographic display device for reconstructing a scene which is divided by software means into object points, with system controller means for computing a computer-generated hologram (CGH) of the scene and for encoding the CGH on a light modulator means, a light source means for illuminating the light modulator means with coherent light, and a reconstruction means for transforming the light in the form of modulated wave fronts into an observer window, from where at least one observer eye sees the holographic reconstructions of the object points which are generated by the modulated wave fronts in a reconstruction space that stretches between observer window and light modulator means and which are superimposed in the observer window, wherein the reconstruction beam path comprises means for temporally or spatially displacing the modulated wave fronts emitted by the light modulator means of each object point which is reconstructed in the reconstruction space such that the reconstruction means multiplies each reconstructed object point with itself caused by this displacement, and that the multiplied reconstructions of each object point are incoherently superimposed with themselves in the observer window.
