    摘要: A system for deriving parallel data from a source, such as a detector array within an enclosed cryogenic volume utilizes remote optical sensing of micromechanical modulators so as to minimize power requirements and heat loss while providing full bandwidth operation. Subgroupings of the detector elements are used in multiplexed fashion to drive high speed micromechanical modulators in binary fashion until the entire detector array has been scanned. The deflection states of the micromechanical modulators are remotely sensed by optical means and the parallel data then reassembled or processed as desired. With this configuration the detector and modulator arrays may be disposed compactly within a cryogenic enclosure and external thermal inputs limited to low levels.

    摘要: A system for processing of multifrequency input signals to provide a Fourier transform output is provided which can, for example, partition a wide input frequency band into a number of narrow bands and concurrently detect the presence of one or more signals of different frequency in the input. An array of input wave energy transducers is energized with the broadband signal, and by virtue of progressive shifting of the transducers relative to the propagating medium (such as a surface acoustic wave substrate) generates one or more composite wavefronts dispersed at frequency dependent angles. An array of output transducers are disposed along a focal region, each responding to wave energy within a specific frequency range received at its location due to dispersion of the composite wavefront. Such systems preserve phase coherence while responding to multiple input frequencies, but are compact and mass producible at relatively low cost.

    摘要: Dynamic variation of the functional properties of a surface acoustic wave (SAW) device is achieved by using photoconductive material on a wave propagating substrate and illuminating the material with changing light patterns. Photoconductive materials, such as lead sulfide or cadmium sulfide, are used that are essentially dielectrics and have substantially no effect on SAW propagation when not illuminated, but under suitable levels of illumination become resistive and interact with the electric fields of the waves to dissipate energy as heat. Scanning control of the areas of illumination may be used to attenuate sidelobes and scattering in a wideband system, while intensity variations may be used to amplitude modulate the waves.

    摘要: An apparatus for indicating the position of a movable member, such as a manual control lever, which uses light signals. The apparatus includes at least three light guides and means for introducing distinctively different, cyclically varying light signals into at least two of the light guides. The degree of optical coupling between the third light guide and each of the other two light guides is controlled in accordance with the position of the movable member. An indication of the position of the member is then provided by detecting the third light signal and indicating the extent to which it exhibits the distinctive characteristics of the first and second light signals.

    摘要: Apparatus for multiplexing or demultiplexing multiple laser beams of different wavelength. In multiplexing, the outputs from multiple diode lasers are combined in such a manner as to produce a practically parallel set of beams for direction onto a diffraction grating. The latter component deflects each beam from its normal path by an angular amount determined from the wavelength of the incident light. The angles of incidence of the multiple beams are chosen to provide angles of diffraction that are practically identical for all wavelengths under consideration. In demultiplexing, similar apparatus includes a diffraction grating to provide angular dispersion of the multiple wavelengths, at least one lens to magnify the angular differences, and a set of detectors positioned in the paths of the dispersed beams of different wavelengths.

    摘要: A beam deflection system for use in optical radar, communications, or optical display apparatus, having the ability to scan multiple "target" clusters that are widely scattered over a large angular field. In its transmission mode of operation, the system switches a laser beam sequentially across an array of focal elements, moving the beam at high speed, since total beam movement across the array is limited to only a few degrees. The system includes an expansion telescope, which expands the succession of beams from the array of focal elements and directs them onto an array of larger, movable optical elements, such as gimbaled mirrors, which direct the successive beams toward scattered target areas in a large angular field. The system also includes a beam scanning device, for "microscanning" the beam through a number of separately resolvable positions within the field of view of each of the array of focal elements.
