摘要： The invention relates to apodization in a holographic direct view display. Known apodization functions are utilized/modified for an apodization mask such that the functions reduce the intensities of selected higher magnitudes of diffractions. The holographic direct view display comprises a controllable light modulator having modulator cells and modulating impinging coherent light into a phase and/or amplitude, and an array of apodization masks. The apodization masks have the same apodization function for a predetermined group of modulator cells, by means of which function a complex amplitude transparency can be set for the modulator cells. This transparency corresponds to an individually predefined course of intensity in a far field of the light modulator, wherein the predefined course of intensity includes a reducing of the light intensity of higher magnitudes of diffractions, and/or of the interfering light emitted by the light modulator.

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： In a pixilated spatial light modulator having a mesh-based modulator element per pixel, a real location-dependent amplitude and a location-dependent phase can be adjusted independently of each other for modulating a coherent wavefront using complex values. A complex-valued spatial light modulator includes a regularly constructed pixel array, wherein each pixel comprises a controllable reflective line mesh. The modulation of the amplitude and phase take place independently of each other in each modulator element, by relative motions of the self-supporting line mesh relative to a base plate. The line meshes are suspended and supported such that both the distance between the base plate and the line mesh (normal adjustment for amplitude modulation) and the lateral displacement of the line mesh in the mesh plane itself (phase modulation) are modified by a system controller. The reflected light is thus modulated independently of each other.

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.
