Abstract: The invention relates to a method for generating video holograms for a holographic reproduction device (HAE) with at least one light modulation means (SLM), wherein a scene (3D-S) split into object points (OP) is encoded as a whole hologram (H? SLM ) and can be seen as a reconstruction from a visibility region (VR), which is located within a periodicity interval of the reconstruction of the video hologram. The visibility region (VR), together with each object point (OP) of the scene (3D-S) to be reconstructed, defines a subhologram (SH) and the whole hologram (H? SLM ) is generated from a superposition of subholograms (SH), wherein in a sequence of image contents the difference subholograms (SD) of object points are preferably generated for each picture, differing in regards to the visibility according to the viewer position (VP) in sequential images (P n-1 , P n ) of the sequence. The display device (HAE) comprises means that provide high-quality video holograms in spite of the data amount being significantly reduced.

Abstract: A holographic projection system with an optical wave tracking system (M1, M2) which sets the propagation direction of a modulated wave uses a position control system and an eye finder. It is the object of the invention to provide an adjustable optical wave correction system which compensates for deformations of the wave which are dependent in particular on the current eye position (PE). Here, besides general aberrations, largely dynamic changes and deformations in the form structure of the modulated and conditioned wave are intended to be reduced, which result predominantly from changes in the propagation direction of the aligned, optically enlarged and modulated wave on a focusing display screen S. According to the invention, the optical wave correction system comprises adjustable wave form means (WFF) and computer means (CU) which set the optical behaviour of the wave form means using the positional data from the current eye position. The adjustable wave form means are located in the light path between an illuminating system for the spatial light modulation means (SLM) and the display screen (S) of the projection system.

Said unit contains a controllable optical matrix (BM) which comprises a plurality of controllable pixels which are regularly arranged, in addition to a finely structured optical mask (LM) which has a raster structure (r) which is defined by imaging elements (L1,L2,...). In order to produce sweet-spots on any particular and predetermined place, p pixels (1,..,p) are associated in a controlled manner with each imaging element and the actual geometry of the raster structure (r*) of the optical mask (LM*) deviates from the regular structure (r ) due to the defectively formed imaging elements (L1*,L2*,..).

Abstract: The invention relates to a method for reconstructing a three-dimensional scene in a holographic display. In said method, the 3D scene that is to be reconstructed is decomposed into object points, and one respective object point is encoded as a sub-hologram in the light modulator. Processor means and reconstruction means are provided for calculating and encoding as well as for reconstructing the 3D scene in order to overcome known drawbacks encountered when encoding a hologram and holographically reconstructing the 3D scene in holographic display devices. According to the proposed solution, processor elements are provided for generating a movable two-dimensional grid in the light modulating means (L), forming groups of object points (OPGm) from grid-related object points (OPn), and sequentially encoding the holograms of said groups of object points (OPGm), by means of which intrinsically coherent partial constructions of the groups of object points (OPGm) are generated in a rapid sequence, said partial constructions being incoherent relative to one another. The wave fronts of reconstructed object points are sequentially superimposed within a visible range such that the reconstruction of the 3D scene can be seen as a time-averaged reconstruction.

Abstract: A reduction in speckle patterns in the reconstruction of a 3D scene can be achieved by way of averaging. In a holographic reconstruction device, speckle patterns are intended to be suppressed while taking account of the visible resolution of the reconstruction of the scene. The holographic reconstruction device is designed such that the visible resolution of the reconstruction of the scene is matched to the resolution capability of the human eye, to the imaging properties of the reconstruction means (RM) used or to the resolution capability of the light modulation means (SLM) used. Method steps are carried out, in which a grid scale for the object points (OP) is generated by way of system control means (SM) in each case in a plane of intersection (SE), which grid scale cannot be used to separately resolve adjacent object points (OP) in the plane of intersection (SE), and the compilation of object points (OP) of the respective plane of intersection (SE) to form an object point group with adjacent object points (OP) which can be separately resolved is carried out. In holographic displays, the invention is used to reduce speckle patterns and reduce the number of the holograms of object points of the scene, which are to be calculated and coded, and the calculation complexity.
