摘要： A holographic reconstruction system is disclosed for the three-dimensional reconstruction of object light spots of a scene, comprising spatial light modulation elements which modulate interference-capable light waves of illumination means with at least one video hologram, and optical focussing elements which focus the modulated light waves with the reconstructed object light spots for at least one eye position of the observer's eyes. An electro-optical deflection element controlled by a system controller focuses the modulated light wave with the reconstructed object light spots on at least one eye position and tracks them when the eye position changes. The electro-optical deflection element is a controllable optical diffraction grating with a variable surface relief structure consisting of separately controllable microcells.

摘要： A light modulating device comprises a spatial light modulator and a homogenizing element. A group of at least two adjacent pixels of the spatial light modulator form a macropixel: The spatial light modulator is of a type such that its pixels comprise a variable content. Each macropixel is used to represent a numerical value which is manifested physically by the states of the pixels of the spatial light modulator which form the macropixel. For each macropixel a homogenizing element is present in the optical path after the macropixel. The homogenizing element comprises an optical input and an optical output. The homogenizing element is adapted such that output light of the macropixel is entering the optical input of the homogenizing element and is mixed within the homogenizing element and is output at the optical output of the homogenizing element.

摘要： A modulation device based on electrowetting cells (EW cells), phase or amplitude or both simultaneously as a complex value of incident light is modulated in each EW cell. An EW cell includes at least one chamber with at least two fluids which are separated by an interface, external and internal electrodes which form electrode pairs activatable by control means, where at least one electrode pair controls the level of the interfaces in the chamber. The internal, mutually functionally independent electrodes inside the chamber are disposed parallel to each other such that the chamber is divided into two communicating sections with two controllable interfaces, where at least one section is transparent and forms the optical path. When at least one electrode pair is activated, the interfaces are mutually displaced such that the path length of the pencils of rays is changed compared with an initial value.

摘要： Disclosed is an illumination unit comprising a strip-type optical wave guide and an imaging means, and providing a very high light efficiency with a reduced number of primary light sources. The illumination unit enables the production of a coherent plane wave field having a temporal and spatial coherence required for holographic reconstructions. The strip-type optical wave guide contains extraction elements for extracting injected coherent light guided into an observer plane by imaging elements via a controllable light modulation means. During the injection of light, the extraction elements form a grid of secondary light sources which are arranged in the front focal plane of the imaging elements and carry out the spatial coherence in at least one dimension. A secondary light source and an imaging element are associated with each other in order to guide the extracted light through the controllable light modulation means in a collimated manner.

摘要： Disclosed is a display for the holographic reconstruction of a three-dimensional scene using means which allow a reduction of speckle patterns. Speckle patterns result in the graining of a holographic reconstruction and worsen the quality thereof. The 3D scene is incoherently superimposed with itself chronologically or spatially in the eye of the observer. The modulated wave fronts of each reconstructed object point of the scene are shifted relative to themselves in the reconstruction beam path and superimposed in the eye of the observer. The shifting may occur one-dimensionally and two-dimensionally. Each object point is multiplied with itself in the eye of the observer in accordance with the number of the shifted wave fronts. The various speckle patterns over which the eye of the observer averages are also multiplied. Speckle patterns are reduced and the reconstruction quality is thus increased in holographic displays.

摘要： A three-dimensional light modulator, of which the pixels are combined to form modulation elements. Each modulation element can be coded with a preset discrete value such that three-dimensionally arranged object points can be holographically reconstructed. The light modulator is characterized in that assigned to the pixels of the modulator are beam splitters or beam combiners which, for each modulation element, combine the light wave parts modulated by the pixels by means of refraction or diffraction on the output side to form a common light beam which exits the modulation element in a set propagation direction.
