Abstract: A method of forming a rarefied hologram for video imaging and 3D lithography by using an MEMS/SLM with a plurality of pixels on the surface at a fixed distance from the retina of the viewer′ eye. The method consists of providing an initial desired image, which has to be holographically reproduced by the MEMS/SLM as a remote virtual 3D image visible by the viewer's eye. The desired image is coded in a special manner and mapped by encoding and calculating only a part of the initial desired image. The operations of the pixels are controlled in accordance with the code for generation of the holographic pattern. Since only a part of a holographic pattern of the image is encoded and calculated, it becomes possible to reduce the calculation time and decrease parasitic light scattering.

Abstract: 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.

Abstract: The invention provides optical interconnects of data-processing cores of multicore chips by means of digital planar holographic microchips. The method comprises delivering “N” laser lights to “N” data-processing cores on the host chip, coding the obtained optical signals by modulating them with the core-generated data, and then delivering the modulated and coded optical signals to a holographic microchip formed on the same substrate of the host chip as the data-processing cores, splitting the modulated and coded optical signals into (N-1)N modulated optical copy signals, delivering the copy signals to all data-processing cores except the one that generates the copy signals, and decoding the data obtained from the output signals delivered to the processing cores by the receivers. The method is efficient in that it allows replacing electrical interconnects between the cores with optical interconnects and can be matched to current semiconductor production technology.

Abstract: A system and method for cancellation of RF interference in the optical domain. The system and method utilize two Mach-Zehnder electrooptic modulators biased for parallel counter-phase modulation. The method of signal subtraction is referred to as incoherent optical subtraction, since two independent laser sources serve as the optical carrier waves. The system has produced the broadband cancellation result while simultaneously recovering a 50 dBm signal which was initially “buried” under the broadband interference. The cancellation depths achieved by the system are due to the accurate channel tracking and precise time delays attainable with modern optical devices—unattainable with state-of-the-art electronic devices at the time of this writing.

Abstract: 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.

Abstract: 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.
