摘要： An optical channel waveguide having a reflection grating and a related method for its fabrication. The grating is apodized to provide a desired reflection or transmission spectral characteristic, by varying the grating width along the length of the grating in the direction of light propagation. The grating has multiple parallel elements extending across the waveguide channel width, and apodization is effected by appropriate selection of the width of each element relative to the width of the channel, without varying the grating duty cycle or other parameters.

摘要： A multi-purpose tool for inserting tanged or tangless wire inserts in a pre-threaded hole. In the case of a tangless insert, the tool nose passes freely through the internal diameter of the insert until a tool pawl automatically engages a cut out formed in the tangless insert. Once the proper depth of the insert in the parent material has been achieved, the tool stops rotating and is reversed for proper disengagement, the installation being complete. In the case of a tanged insert, the nose of the tool does not pass freely through the insert due to the presence of the tang that is blocking its way. As the tool rotates through the internal diameter of the insert, a ledge formed on the nose portion of the tool forces the insert to wind itself in the threads of the parent material. The pawl used to install the tangless insert is positioned directly behind the nose of the tool and remains inoperable in the retracted position since the insert does not have a cut out provided for it. After proper depth of the insert has been achieved, the tool stops rotating and is reversed for proper disengagement.

摘要： A multispectral imaging system (1) and method utilize an optical processor (3) for simultaneously comparing an input wavelength spectrum observed in a single spatial pixel in a scene image from a multispectral imager (2) with a plurality of template wavelength spectra to find a correlation. The optical processor exploits the three-dimensional attributes of optical correlation to perform massively parallel correlation processing by modulating (4) respective ones of a plurality of spectral bands of the input wavelength spectrum of an incident light beam (6) with modulating elements (5) to alter at least one property of the incident light beam by a value corresponding to the observed intensity of the input spectrum in the respective spectral band. In a disclosed embodiment, the modulated beam is expanded and transited through a spatial light modulator (7) having a two-dimensional array of modulating elements. Each row of the elements of the array alter the at least one property of the incident light by values corresponding to a particular template wavelength spectrum of a plurality of template wavelength spectra of the modulator. The values corresponding to each template spectrum are the conjugates of the representative values of the modulating elements of the template spectrum of the plurality of template spectra.

摘要： A tunable, integrated WDM optic couler for coupling optical energy to and from channel waveguides in response to the application of Surface Acoustic Waves (SAW's ), and a distributed processor computer control system utilizing the couplers. A first range of SAW's is used to couple optical energy of selected wavelengths from a channel waveguide driven by a LED to multiplex optical energy to a common optic loop and a second, non-overlapping range of SAW's is used to couple optical energy from the loop to a second channel waveguide. The second, receiving channel waveguide includes a Bragg deflector, planar waveguide and photodetector arrays to demultiplex the optical energy by focusing selected wavelengths of optical energy on selected portions of the photodetector arrays. Changes in the acoustic wavelengths and amplitudes permit tuning of the coupler and computer system by altering the portion and wavelengths, respectively, of optical energy coupled by each section of each coupler.

摘要： Described herein is an integrated acousto-optic circuit for analyzing the spectrum of a radar signal. A waveguided optical beam is first split into two parts, one of which interacts with a surface acoustic wave generated by a reference signal and the second of which interacts with a surface acoustic wave generated by the signal to be analyzed. The two resulting phase-modulated optical waves then are recombined, Fourier transformed by a lens and finally caused to impinge on an array of photodetectors. The array of detectors is arranged so that each element of the array responds to the combination of one component of the time-varying signal to be analyzed and one component of the time-varying reference signal, that response being an output signal at some preselected radio frequency which is proportional to the amplitude of the frequency component of the radar signal to be analyzed. The several optical components are disclosed as formed on a single substrate integrated optical circuit.

摘要： Combustion gas such as air, oxygen-enriched air or oxygen is introduced to a calcining zone at an intermediate level in a vertical shaft kiln for the calcining of petroleum coke utilizing a plurality of radially disposed combustion gas injectors and at least one vertically disposed injector located within the shaft kiln and extending into the calcining zone. The injector includes means for circulating coolant around the periphery of the injector so that common metals may be used in the high temperature (above 2000.degree. F.) environment of the shaft kiln. The vertical combustion gas injector may extend from the top of the calcining chamber to the calcining zone or from the bottom of the calcining chamber to the calcining zone. When the vertical combustion gas injector extends vertically upwardly from the bottom of the calcining chamber, means for introducing recycle gas to the calcining chamber may be incorporated into the vertical combustion gas injector.
