Abstract: An optical memory is disclosed in which data is stored in an optical data layer capable of selectively altering light such as by changeable transmissivity, reflectivity, polarization, and/or phase. The data is illuminated by controllable light sources and an array of multi-surface imaging lenslets project the image onto a common array of light sensors. Data is organized into a plurality of regions or patches (called pages) and by selective illumination of each data page, one of the lenslets images the selected data page onto the light sensors. Light in the data image pattern strikes different ones of the arrayed light sensors, thereby outputting a pattern of binary bits in the form of electrical data signals. By selectively and sequentially illuminating different ones of the data regions (pages) on the data layer, correspondingly different data patterns are imaged by the corresponding lenslets onto the common sensor array, thereby enabling many stored data pages to be retrieved by multiplexing at electro-optical speed.

Abstract: An optical memory stores data in an optical data layer capable of selecting altering light such as by changeable transmissivity. Data is organized into a plurality of regions or patches (called pages) in which each page contains a field of data spots storing binary data as the presence or absence of a hole. The data is illuminated by controllable light sources and an array of single element diffractive imaging lenslets, one for each data page, projects the image onto a common array of light sensors. By selective illumination of each data page, one of the single element lenslets images the selected data page of holes onto the light sensors. By selecting a hole size and using a certain range of restricted acceptance angle grooves on the diffractive elements, the data image is optimized for a single diffractive element lens.

Abstract: A method of and device for calibrating infrared radiation transducers. A concentration factor representing the ratio of a data signal to a reference signal for a known concentration of a designated gas in a sample containing that gas is generated. The concentration factor is stored and used during subsequent calibration procedures. The calibration device has a zero cell and a span cell with windows for transmitting infrared radiation and radiation reflecting or absorbing material in the span cell.

Abstract: An optical data record playback apparatus is described for simultaneously scanning a plurality of data tracks on the optical record by employing two or more light beams controlled by closed loop servos. First and second optical servo means respectively, are employed to deflect the light beams for tracking of such beams during scanning along the data tracks and for maintaining the proper spacing between beams to cause each beam to follow a different track. In addition, a time adjust means, which may be a third optical servo or an electronic signal delay means, is employed to adjust the time relationship of the two readout signals produced by such light beams. The optical servos may include either movable mirrors or light refraction plates. Alternatively, an electromagnetically deflected bundle of optical fibers can be employed as the first servo and a zoom lens at the output of such fibers as the second servo. Also, a double refraction polarizing device, such as a calcite crystal, can be employed as both the second and third servos by pivoting such crystal about two mutually perpendicular axes.

Abstract: An optical fiber deflection device is described in which an electrical transducer is used for deflecting the fiber in response to an electrical control signal in order to deflect a light beam transmitted through such fiber. The transducer includes a nonmagnetic deflector means attached to the fiber and connected to an electrical current source, for deflection of the fiber by movement of the deflector means. In one embodiment employing an electromagnetic transducer, an electrical conductor is attached along the length of the fiber and is connected to a D.C. current source to produce a magnetic field around the conductor so that they may be deflected by pairs of electromagnetic coils positioned adjacent the side of the conductor when a control signal is applied to such coils. Alternatively, the control signal can be applied to the conductor attached to the optical fiber and a D.C. current caused to flow through the electromagnetic coils. Other embodiments of the invention use a piezoelectric transducer means including a piezoelectric element attached to the optical fiber so that they are deflected in response to a control signal applied to such element. In still another embodiment of the invention, the electromagnetic transducer means includes electromagnetic coils provided around a pair of magnetostrictive wires each having one end fixed and their other ends attached to the fiber, so that such wires expand and contract to deflect the fiber when a control signal is applied to such coils. In a further embodiment, a thermoelectric transducer means is used including a thermal expansion element, such as a bimetal strip, attached to the fiber and an electrical heating element supported adjacent to such expansion member so that when a control signal is applied to such heating element, the expansion member bends an amount corresponding to the current of such signal to deflect the fiber.

Abstract: A scanner such as a bar-code scanner includes a scan-beam generator, a beam reflector having a first magnet, and a beam-sweep mechanism having a second magnet. The beam-sweep mechanism causes the reflector to sweep the scan beam across a target such as a bar-code symbol by exerting a force on the first magnet with the second magnet. In one example, attraction between the magnets holds the reflector steady in a non-sweep position. Conversely, in a sweep position, repulsion between the magnets causes the reflector to oscillate and sweep the scan beam across a target such as a bar-code symbol. Because it does not include a motor for rotating a beam-sweep mirror, the scanner is often smaller and uses less electrical energy than motorized bar-code scanners.

Abstract: A compact optical memory is disclosed in which data are stored in an optical data layer capable of selectively altering light such as by changeable transmissivity, reflectivity, polarization, and/or phase. The data are illuminated by controllable light sources and an array of multi-surface diffractive imaging lenslets which cause a data image to be projected onto an array of light sensors by reflecting, hence folding the image rays, by means of a Mangin mirror that both reflects and optically modifies the light rays to redirect them onto the sensor array located substantially coplanar with the data layer. Data are organized into an annular array of patches (called pages). By selective illumination of each data page, one of the lenslets images the selected data page onto a central image plane where the sensor array is located. Light in the data image pattern strikes different ones of the arrayed light sensors, thereby outputting a pattern of binary bits in the form of electrical data signals. By selectively and sequentially illuminating different ones of the data regions (pages) on the data layer, correspondingly different data patterns are imaged by the corresponding lenslets onto the common sensor array, thereby enabling many stored data images to be retrieved by multiplexing at electro-optical speed.
