摘要： A fully parallel CCD memory chip of N address lines which detects in just one clock cycle, a perfect match between an input pattern and any of a plurality of stored patterns and also detects in less than (N+1)-comparison cycles and still just one XOR operation, the best matching in case a perfect one does not exist. The chip disclosed herein has a fully parallel architecture in which an input word is compared to all stored words at one time. A preferred embodiment of the invention uses a four phase CCD, wherein each stored word occupies one row of the CCD and each such bit of each such word occupies two cells. Where perfect matches exist, only one comparison clock cycle is needed to compare the input word with all stored words and where there is no perfect match, the best match will be detected on a subsequent comparison pulse. Charge packets represent binary words generated by external pulses that are applied to the chip through data input lines and then are compared to the data applied to the address lines. The sensing is done directly on the cells in a non-destructive sensing process in parallel, rather than at the end of each row.

摘要： An all-optical, self-aligning, holographic phase modulation and motion sensing apparatus includes a crystal exhibiting a zero electric field photorefractive effect, a phase modulation or vibration source or mechanism, a source of coherent optical radiation, beam splitting and directing optics, and at least one optical radiation detector. The output from the optical radiation source is split into separate beams, one or all of which are phase modulated. The beams are directed through the crystal exhibiting a zero electric field photorefractive effect, and the resultant transmitted beams are detected by an optical radiation detector to provide a measurement of the phase modulation of the beams. The sensor functions in the absence of an electric field because of the unique characteristic of the crystal exhibiting the zero electric field photorefractive effect whereby if either the phase of the crystal's index grating or of the interfering beams is modulated with a phase change very much less than .pi./2, the intensity of the beam transmitted through the crystal varies linearly with the modulation. Such linear modulation allows crystals exhibiting the zero electric field photorefractive effect to remotely sense phase modulations or vibrations of any type in the absence of electrical signals in the vicinity of the sensor.

摘要： An adjustable CCD gate structure utilizing ultra-violet light activated floating gates, wherein a floating polysilicon gate is used between a CCD electrode and the underlying substrate to provide a fixed voltage bias to the CCD gate during the manufacturing process thereof The floating gate is programmed with a desired voltage bias during the application of ultra-violet light and is thereafter fixed at that adjusted level, upon the removal of the ultra-violet light. Thus, the method of the present invention comprises the steps of providing a CCD gate structure in which there is such a floating polysilicon gate between the CCD electrode and the underlying substrate; applying an ultra-violet light activation to the floating polysilicon gate; applying a voltage to the conventional CCD electrode which is resistively coupled to the floating electrode for adjusting the bias on the floating electrode to a desired level; and then removing the ultra-violet light to fix the voltage bias at the floating polysilicon gate at a permanant level.

摘要： A passive (self-pumped) phase conjugate mirror uses a third-order nonlinear polarization medium, either of the refractive type (effective nonlinear) or the actual nonlinear type, with an optical system of one or more mirrors to reflect back through the medium a coherent incident beam diffracted by the medium. With two mirrors, they may be aligned to form a linear optical cavity containing the nonlinear medium, or they may be so oriented on one side of the medium that the incident beam transmitted through the medium is reflected back through the medium at an angle with the incident beam, and diffracted light from the incident beam is reflected back through the medium in the opposite direction coincident with the incident beam. A passive phase conjugate mirror may replace an end mirror of an optical cavity for a laser gain medium. Phase distortions of the laser beam in the laser cavity are corrected by the passive phase conjugate mirror.
