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： The frontlight illumination system is intended for enhancing illumination of a reflective display having pixels arranged in a matrix pattern and using monochromatic laser lights as light sources. The unit contains a network of light-distributing planar ridge waveguides with holograms arranged in a matrix pattern that corresponds to the matrix pattern of the reflective display. The light-distributing holograms of the system are formed on opposite sides of each core of respective light-distributing planar ridge waveguides. Neighboring holograms located on opposite sides of the core are combined into pairs and are arranged on each core in positions at which they interact with a predetermined phase shift that doubles the intensity of light directed to the reflective display and extinguishes light directed to the external surface.

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： A method and apparatus for remotely monitoring properties of gases and plasmas, and surface and sub-surface properties of materials, is disclosed. A laser beam is focused at a desired region within a gas, plasma, or material (e.g., solid or liquid) to be analyzed, generating an ionized sample region or a localized, enhanced free carrier region. A beam of microwave radiation is directed toward the ionized sample region or the free carrier region, and the microwave radiation is scattered. The scattered microwave radiation is received by a microwave receiver, and is processed by a microwave detection system to determine properties of the gas, plasma, or material, including surface and sub-surface properties.
