摘要： Disclosed is a method for reducing speckling in liquid crystal displays with coherent illumination. The method consists of providing a liquid-crystal display illuminated, e.g., with a laser light, in which the image is formed by passing the light through the light redirecting holographic elements arranged in a matrix pattern, then changing the direction of the beams emitted from the holographic elements by passing the emitted beams through the polarization-changing liquid crystal elements, and converting the image-carrying beams produced by the liquid crystal elements into a visible image by passing them to a viewer through a polarization analyzer.

摘要： Proposed is a speckle-reduced laser illumination device that may be used in optical microscopy, machine vision systems with laser illumination, fine optical metrology, etc. The device comprises a net of planar ridge waveguides formed into an arbitrary configuration and having a plurality of holograms with holographic elements formed into a predetermined organization defined by the shape of a given light spot or light field which is to be formed by light beams emitted from holograms on the surface of an object or in a space and at a distance from the planar ridge waveguide. Speckling is reduced due to the fact that at least a part or all of the holograms are spaced from each other at distances equal to or greater than the coherence length. The geometry and organization of the holographic elements allow position control of the light spot and beam converging and diverging.

摘要： This invention relates to autostereoscopic display assemblies, in particular for hand-held devices such as tablets, i-Pads, mobile phones, etc., wherein a stereoscopic effect is achieved by forming light beams are emitted from the display at different angles and with different polarization. The display assembly comprises a sandwiched structure consisting of a light-guide panel and a modified liquid-crystal display that is applied onto the light-guide panel. The panel has on its outer surface a net of light waveguides for delivery of light from the light source and for uniform distribution of light over the entire surface of the display. The different polarizations and angular directions of the beams perceived differently by a viewer's left and right eyes are achieved by providing the light-distribution waveguides with holograms of two different types.

摘要： Disclosed is a liquid-crystal display with coherent illumination. The display has a multilayered matrix structure comprising a matrix of micromirrors, lightguide panel with a matrix of holographic elements, a liquid-crystal matrix containing a plurality of liquid-crystal cells and a polarization analyzer. The micromirrors perform reciprocating linear or tilting movements. Therefore, in each current moment, the speckle pattern of the image shifts relative to the preceding pattern so that in each current moment the viewer sees an image in different micropositions, which are perceptible by the human eye as a quasistationary pattern. As a result, the speckle pattern seen by the viewer is smoothened.

摘要： The invention relates to a light-guide panel for an LCD with a laser backlight. The panel comprises a laser light source and a main ridge waveguide with a plurality of first holograms that change the direction of the laser light that propagates along the main ridge waveguide to the direction perpendicular to the latter. The first holograms are associated with thee light of predetermined wavelengths and are optically connected to respective transverse waveguides that lie in the same plane but are perpendicular to the main ridge waveguide. Each transverse ridge waveguide has a plurality of second holograms designed so that they change the direction of laser light that propagates along the transverse ridge waveguide in the direction at an angle to the plane of the LGP substrate. This angle should be close to 90° and may be obtained in the range of 70° to 85°.
