    摘要： The invention relates to a light modulation device for a display for representing two- and/or three-dimensional image content or image sequences. The light modulation device comprises a light modulator and a controller. The phase and/or the amplitude of a light wave field, which is substantially collimated, can be varied by means of the light modulator depending on the location of the light modulator. The light modulator can be actuated by means of the control device. According to the invention, in the direction of propagation of the light wave field, at least one diffracting unit is arranged downstream of the light modulator. The diffracting unit has a variable diffracting structure. By means of the diffracting structure, the light wave field varied by the light modulator 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.

    摘要： An optical component deflects light beams which pass though the optical component. The optical component comprises multiple fluid cells arranged next to each other in a regular structure, and an influencing means, where a fluid cell contains at least two immiscible fluids, where an interface will form between two fluids of a fluid cell, where the interface can be given a specifiable shape and/or orientation by the influencing means, where a fluid cell comprises at least one optical medium, where the optical medium is disposed adjacent to a fluid of the fluid cell, where the shape of the surface of the optical medium which faces the adjacently arranged fluid cannot be changed, and where the optical medium serves to deflect the light beams which pass through the fluid cell by a specifiable angle.

    摘要： A holographic reconstruction system is disclosed with spatial light modulation means, modulating interferable light waves from light sources with at least one video hologram, comprising optical focusing means, focusing the modulated light waves with the reconstructed object light points for at least one eye position for the eyes of observers and controllable electro-optical deflector means, which direct the focused modulated light waves with the reconstructed light points to at least one eye position in order to reduce the aberrations. The reconstruction system has the optical focusing means in a field of focusing elements, wherein each focusing element is provided with at least one interferable light source. The electro-optical deflector means lie in the light path of the interferable light waves after the optical focusing mean and have at least one field of deflector elements, which has at least one separately controllable electro-optical deflector element for each focusing element.

    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.
