Abstract: An infrared (IR) simulator is disclosed in which an array of pixels is defined on an insulative substrate by resistor bridges which contact the substrate at spaced locations and are separated from the substrate, and thereby thermally insulated therefrom, between the contact locations. Semiconductor drive circuits on the substrate enable desired current flows through the resistor bridges in response to input control signals, thereby establishing the appropriate IR radiation from each of the pixels. The drive circuits and also at least some of the electrical lead lines are preferably located under the resistor bridges. A thermal reflector below each bridge shields the drive circuit and reflects radiation to enhance the IR output. The drive circuits employ sample and hold circuits which produce a substantially flicker-free operation, with the resistor bridges being impedance matched with their respective drive circuits. The resistor bridges may be formed by coating insulative base bridges with a resistive layer having the desired properties, and overcoating the resistive layers with a thermally emissive material. The array is preferably formed on a silicon-on-sapphire (SOS) wafer.

Abstract: A system and method are described for achieving a high efficiency, full color display using color sensitive lenses such as holographic lenses. A lens assembly is composed of discrete lens elements (1, 2, 3) which are sensitive to different wavelengths bands of light. Each lens element (1, 2, 3) focuses input light within its waveband onto a corresponding target area, and generally transmits input light outside of its waveband. A separate target area (R, G, B) is provided for each lens element, whereby incoming light is divided into its constituent colors. The separate color stripes (R, G, B) may then be operated upon to produce a desired display. For incoming light which is to be divided into n different wavebands and directed onto separate target areas each having an area A, the area of each lens element is approximately nA, and each lens overlaps the next adjacent lens by an area approximately equal to (n-1)A. By generally transmitting rather than absorbing light outside the band of each lens element, the assembly achieves a high degree of both efficiency and resolution. Specific applications to various types of flat-panel displays and light valves are disclosed, as well as preferred fabrication techniques for the holographic lenses.

Abstract: A column interconnecting and full array interconnecting functional plane (240) for simultaneously transferring data to and from the data exchange subsystems (74) of the array processor (61). This functional plane nominally includes an array of pseudo-modules (242, 244, 246) that architecturally corresponds to the module arrays of the other functional planes of the array processor. Thus, a pseudo-module is present in each of the elemental processors. These pseudo-modules are associated as columns that are each interconnected by an interconnecting plane column data exchange subsystem (256). These columns are, in turn, associated with column control logic circuits (248, 250) that each include a column memory register. A mode decode logic circuit (252) establishes the operating configuration of the column control logic circuits. The interconnecting functional plane (240) can be selectively configured for a number of different modes. These modes provide for the transfer of data: (1) from the control processor (10) commonly to all of the data exchange subsystems (74) of the array processor (61), (2) from the top row, corner pseudo-module's (246) data exchange subsystem commonly to the remaining data exchange subsystems (256), (3) from the column memory registers commonly to the data exchange subsystems (256) of their respective columns of pseudo-modules (242, 244, 246), (4) from the data exchange subsystems of the top row of pseudo-modules (244, 246) commonly to the data exchange subsystems (256) of their respective columns of pseudo-modules (242, 244, 246), (5) ORed from all of the data exchange subsystems (74) of the array processor (61) to the control processor (10), and (6) ORed from the data exchange subsystem (256) of each column of pseudo-modules to their respective column memory registers. Utility modes for transferring data between the control processor (10) and the column memory registers are also provided.

Abstract: The present invention provides improvements to an array processor for analyzing two dimensional arrays of spatially related data elements. More specifically, provision is made to permit a cellular array processor (10) to efficiently perform data dependent processing such as floating point arithmetic functions. In the preferred embodiment, one module (84) in the array processor (12) generates a signal applied to bus line (24) when all of the bits in a register (86) are zero. The signal on bus line (24) effects the shifting operation of a shift register (36) in a memory module (34) located on a different functional plane. Thus, the processing functions carried out in each elemental processor (26) can be made to depend on the value of data stored therein instead of being dictated solely by a simultaneous executed instruction from the control processor (14) as is the normal case.

Abstract: A single-Schottky liquid crystal is dis­ closed in which a series of Schottky contacts are made on one side of a photoconductor substrate by a metal matrix mirror, with a doped semiconductor back contact electrode on the other side of the substrate. The light valve offers several operational advantages over MOS devices, and is easier to fabricate than double-Schottky light valves. It can be operated either in an AC mode or, by doping the liquid crystal ions, in a DC mode.

Abstract: Procédé de fabrication d'un dispositif à semiconducteurs par fusion à zone de gradient thermique, dans lequel des gouttelettes (24) riches en métal tel que de l'aluminium migrent au travers d'une tranche de semiconducteur (14) telle que du silicium pour créer des chemins conducteurs (22). Une surface de la tranche (14) est placée à proximité étroite d'une source de chaleur (42) de manière à établir un gradient thermique élevé et uniforme au travers de la tranche (14). La chaleur dans la tranche (14) est extraite de l'autre surface de la tranche. Le dispositif permettant d'exécuter ce procédé comprend une base (40), un organe de chauffage (44) et un dissipateur thermique (46). L'organe de chauffage (40) comprend une plate-forme (40) possédant une surface de chauffage généralement plane (42) pouvant recevoir toute la zone de surface d'au moins une tranche (14). Le dissipateur thermique (46) est écarté de l'autre surface de la tranche et délimite un espace (48) adapté pour recevoir un gaz à conduction thermique élevée. Le dissipateur thermique (46) et le gaz tirent de concert la chaleur de la tranche (14) pour faciliter l'établissement du gradient thermique. Une surface de la tranche peut être pourvue d'une couche-tampon (70), qui est placée directement sur une surface de chauffage (42). La couche tampon (70) arrête la migration des gouttelettes pour empêcher la création d'alliage entre les gouttelettes et la surface de chauffage (42).

Abstract: A programmable optical data processor is described as an apparatus for processing an optical data beam comprising a plurality of zero, one and two-dimensional modulators for spatially modulating the optical data beam, means for the lensless interconnection of each of the modulators to provide for the focusless transfer of the optical data beam between the modulators, and means for controlling the plurality of modulators so as to permit the programmable processing of the optical data beam. The optical data processor realized is physically solid and compact and is readily capable of performing a wide variety of optical computations.
