Abstract: A display device comprises red, green, and blue laser sources; a Spatial Light Modulator (SLM) comprising at least one diffraction grating (10) recorded in an electrically variable refractive index material; a control circuit coupled to the SLM; an image generator; and a light stop (20). The SLM is illuminated with a red light at a first angle, green light at a second angle and blue light at a third angle which defines a viewing direction. Diffracted red and green light and undiffracted blue light emerge from the SLM in the viewing direction. Undiffracted red and green light and diffracted blue light are blocked by the stop after emerging from the SLM. I one embodiment, the SLM comprises one Bragg grating which diffracts red and green light into the viewing direction and the blue light away from the viewing direction. In another embodiment, the SLM comprises superimposed red, green and blue diffracting Bragg gratings.

Abstract: A coding technique (1300) encodes each pulse of a pulse stream as a pair of pulses (1316). The scheme is used with gates (1302) that produce an output only when pulses are separated by a specified interval. Using multiple such gates, a signal with symbols defined by different pulses spacings will select only the symbol matching a particular gate configuration. This can be used to route the symbols. The basic technique can be expanded for use with multiple layers of gates.

Abstract translation: 编码技术（1300）将脉冲流的每个脉冲编码为一对脉冲（1316）。 该方案与门（1302）一起使用，仅当脉冲以指定的间隔分开时才产生输出。 使用多个这样的门，具有由不同脉冲间隔定义的符号的信号将仅选择匹配特定门配置的符号。 这可以用于路由符号。 可以扩展基本技术，以便与多层门一起使用。

Abstract: Optical system (200), which control interference pattern (150) of combined grating (100), by controling difference illuminations of beams (132, 134) on grating. Optical fiber (202) guides and emits beams toward leans (204) that converts beam to parallel beam. Beam is the information carrier beam used in optical communication. Reflector (206) receives beam and reflects beam toward attentuator, which transmits beam toward transparent block (104). Beam enters block without direction change and propagates in block toward grating layer (106) of combined grating.

Abstract: A diffraction grating device (100) has both reflecting (106) and transmitting (108) gratings interleaved to allow both transmission diffraction patterns and reflection diffraction patterns to be formed by means of the same device (102). This makes it possible, for example, to produce a diffraction pattern of one order with a beam (132, 134) directed to be diffracted by the reflecting diffraction grating or with a beam directed to be diffracted by the transmitting diffraction grating when either beam is incident alone. It also makes it possible to generate a diffraction pattern of a different order when both beams are incident simultaneously, which reduces effective order of the grating.

Abstract: An electronically variable light attenuator and method for electronically attenuating light having an array of liquid crystal regions is described. The regions in a first set thereof are interspersed with the regions in a second set thereof. The regions in the first set are configured to produce a first diffraction pattern in response to the received light and the regions in the second set are configured to produce a second diffraction pattern in response to the received light. A pair of electrodes are arranged to enable the first and second diffraction patterns to combine with a degree of interference along an axis selected in accordance with an electric field produced between the pair of electrodes and through the at least one of the sets of regions. The array degree of interference is greatest in the absence of the electric field.

Abstract: An optical medium of a mixture of liquid crystal and a polymer precursor is disposed between a pair of glass substrates (1202) and exposed to light, e.g., in the form of interference fringes having a wavelength of about 515 nm and produced using a laser beam of an Ar laser for about 5 minutes, while heated at, e.g., 50 DEG to 70 DEG C. On starting exposure, the polymer precursor starts to be cured (first stage), and periodically arranged polymer columns (1203) are formed, as shown in Figure 10(a). When the exposure is further continued, liquid crystal molecules gathering in dark regions are aligned macroscopically uniformly perpendicularly to the walls of the cured polymer columns (1203), as shown in Figure 10(b) (second stage). A diffraction optical device thus fabricated exhibits a high polarized-light selectivity and a high diffraction efficiency. A polarized light illuminator and an image display comprising such a diffraction optical device can realize display of a bright and high-contrast image.

Abstract: The present invention provides a visual display including a high resolution miniature display compatible with VLSI technology and an optical system such as an optical magnifier used to enlarge the images display on the miniature display to be visible to the naked eye. The miniature display includes a VLSI backplane having an array of display elements monolithically formed with its driving circuit on a single crystalline semiconductor. Signal processing circuit or a microprocessor used to process image signals for the display may also be formed monolithically with the array and its driving circuit. The array may be designed using a software silicon compiler program to have randomly displaced elements or superpixels for reducing image aliasing. The array may also be designed to have display elements positioned and scaled to compensate for the optical distortion introduced by the magnifier. A color microdisplay utilizes diffraction gratings to provide an array of high efficiency color pixels. The microdisplay includes a semiconductor substrate and source of light disposed adjacent thereto. A cover plate may be disposed above the substrate and has a layer of conductive material on a surface of the cover plate opposite the substrate. An optically active material, such as liquid crystal material, may be disposed between the substrate and the cover plate. An array of pixels are formed on the substrate. The pixel array includes an array of diffraction grating elements. Each element includes one or more diffraction gratings. The pitch of each diffraction grating can be a function of the angle of the incident light and the desired diffraction output spectrum. An optical system directs the diffracted light from each grating through the optically active material into viewing optics.
