    摘要: A channel electron multiplier is described having a tubular wall coated w a secondary-electron emitting material and including an electric field for accelerating the electrons, the electric field comprising a plurality of low-resistive conductive rings each alternating with a high-resistive insulating ring. The thickness of the low-resistive rings is many times larger than that of the high-resistive rings, being in the order of tens of microns for the low-resistive rings and at least one order of magnitude lower for the high-resistive rings; and the diameter of the channel tubular walls is also many times larger than the thickness of the high-resistive rings. Both single-channel and multiple-channel electron multipliers are described. A very important advantage, particularly in making multiple-channel multipliers, is the simplicity of the procedure that may be used in constructing such multipliers. Other operational advantages are described.

    摘要: An adaptive optics system is disclosed which has a phase detector to detect phase distortions acquired by an input beam, and a separate phase adjustor which predistorts a transmission beam so that it is restored to its proper phase during transmission back through the same medium travelled by the input beam. The phase adjustor consists of a liquid crystal mechanism with an area substantially greater than that of the phase detector, thereby permitting high power operation. Liquid crystal pixels in the phase adjustor have dual transistor signal storage circuits which apply operating signals to the pixels without significant decay or flicker. The phase adjustor can be constructed in either a reflective or transmissive mode. Two phase adjustors may be placed in series to enhance response time and/or process an unpolarized beam. A data processor interfaces between the phase detector and phase adjustor. The data processor may include a capability for providing phase adjustment information for a plurality of transmission wavelengths based upon the detected distortion of an input beam at only one of the wavelengths.

    摘要: A cellular array processor (10) for efficiently performing data dependent processing such as floating point arithmetic functions. 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.

    摘要: 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 approxmately 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.

    摘要: A column shorted and full array shorted functional plane for simultaneously transferring, or shorting, data to and from the data exchange subsystems of the array processor. This functional plane nominally includes an array of pseudo-modules 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 a shorted plane column data exchange subsystem. These columns are, in turn, associated with column control logic circuits that each include a column memory register. A mode decode logic circuit establishes the operating configuration of the column control logic circuits.
