| The invention relates to a light modulation device (10) for a display for representing two- and/or three-dimensional image content or image sequences. The light modulation device (10) comprises a light modulator (12) and a controller (14). The phase and/or the amplitude of a light wave field (16), which is substantially collimated, can be varied by means of the light modulator (12) depending on the location of the light modulator (12). The light modulator (12) can be actuated by means of the control device (14). According to the invention, in the direction of propagation of the light wave field (16), at least one diffracting unit (20, 38) is arranged downstream of the light modulator (12). The diffracting unit (20, 38) has a variable diffracting structure (22). By means of the diffracting structure (22), the light wave field (16) varied by the light modulator (12) can be diffracted in a variable and predeterminable manner. Further, the present invention relates to a display and a method for producing a light modulation device. | ||||||

| The invention comprises a pattern generation unit (20), a programmable lighting means and a holographic screen (28) that together make a holographic volumetric display. The holographic screen contains a pre-recorded set of volume elements or voxels (32) in three dimensional space outside the plane of the holographic screen. The holographic screen comprises a series of sub-holograms where each sub-hologram is associated with a voxel such that the voxel may be reconstructed when the sub-hologram is illuminated. A sub- hologram is a sampled hologram of a voxel and sub-holograms are spatially multiplexed and interleaved across the surface of the holographic screen. The programmable lighting means may be provided by a colour digital projection unit (28) and the pattern generation unit which can illuminate any number of sub-holograms on the holographic screen. In this way, a volumetric display with holographic voxels can be made. The holographic volumetric display can reconstruct three-dimensional moving images in colour. | ||||||

| A diffractive display suitable for presenting graphic displays is disclosed. One embodiment includes a holographic diffraction pattern (100) carried by a permanent magnet (120) or related element and an electrically energizable coil or conductor (160) energizable for causing movement of the magnet. Rotation of the holographic diffraction pattern about a pivot (140) generates a display with diffracted light from the holographic diffraction grating. Another embodiment includes a faceted rotatable element (FRE) having an array of facets each bearing a diffraction grating and a source energizable for rotation of the FRE from a resting station to a viewing station. Rotation of the FRE generates a display from the diffracted light. | ||||||
