摘要： An improved image transmission system which includes an elongate optical waveguide 15 having an input aperture 17 and an output aperture 19. Optical apparatus 11, 13 is provided for injecting a transform of an image into the waveguide. In a specific implementation, the Fourier transform of the image is injected at the input aperture 17. The output image is transformed as well to provide the desired image. When the Fourier components of the image are transmitted, each component propagates at a different velocity. However, the magnitude of the components are preserved and used to reconstruct the image at the output of the waveguide. This allows for the transmission of optical images without digitization with a single, inexpensive waveguide.

摘要： A nondestructive method and apparatus is disclosed for determining the thickness and composition of a zinc phosphate layer applied to a metal surface, such as sheet metal on an automotive assembly line. The phosphate layer is irradiated with infrared light which is at least partially transmitted through the phosphate layer. Reflections from the upper and lower surfaces of the phosphate layer return a total reflected intensity which is a function of the optical parameters of the phosphate components and the ratio of the components corresponding to the optical parameters. In the event, for example, that a phosphate layer includes two zinc phosphate components, the measure of reflected intensity at two separate wavelengths will be different inasmuch as the optical properties of the zinc phosphate components is also a function of frequency. The measured reflected intensity and its functional dependence upon the ratio of the components within the phosphate layer can be taken together with the known values of the optical parameters of each component to compute the fraction of each component within the phosphate layer.

摘要： A fiber optic fuel or liquid level gauge is disclosed which determines the liquid level by measuring the amount of light loss due to evanescent transfer to the fuel or liquid. An optical fiber is supported in the fuel or liquid tank, with a first end adjacent the highest possible liquid level to be measured with a reflector at the first end. The optical fiber extends downwardly through the tank, and its second end is connected to a light source for injecting light into the fiber. The intensity of the input light is compared to the intensity of light reflected from the first fiber end, and the liquid level is calculated from the light loss. The gauge has very high reliability since it has no moving mechanical parts.

摘要： An X-ray and Gamma ray waveguide, cavity, and method for directing electromagnetic radiation of the X-ray, Gamma ray, and extreme ultraviolet wavelengths. A hollow fiber is used as the waveguide and is manufactured from a material having an index of refraction less than unity for these wavelengths. The internal diameter of the hollow fiber waveguide and the radius of curvature for the waveguide are selectively predetermined in light of the wavelength of the transmitted radiation to minimize losses. The electromagnetic radiation is obtained from any suitable source and upon introduction into the waveguide is transmitted along a curvilinear path. The waveguide may be formed as a closed loop to create a cavity or may be used to direct the electromagnetic radiation to a utilization site.

摘要： Latent fingerprints are detected by upconverting infrared radiation provided by a special dusting powder and digitally imaging the upconverted radiation. In accordance with the principles of the present invention, a real time image of latent fingerprints is obtained by first "dusting" the print with a powdered upconversion material. The print is then illuminated with 1.55 .mu.m infrared radiation using a fiber optic bundle in the form of a probe. The 1.55 .mu.m infrared radiation is converted into several reradiated wavelength bands by the powdered upconversion material. A charge coupled device or diode matrix detector array converts the image of the fingerprint to digital format for real time display and/or transmission over airwaves. The system is a portable latent fingerprint acquisition system that permits rapid fingerprint evaluation and comparison. A method of detecting fingerprints is also disclosed.

摘要： A stimulated Brillouin scattering (SBS) ring laser gyroscope. The SBS laser gyroscope is fabricated from a single-mode optical fiber waveguide and is optically coupled to a laser to accommodate being pumped in two directions by laser radiation having sufficient energy to induce stimulated Brillouin scattering radiation (SBS). The apparatus includes means for extracting a portion of each of the SBS radiation from the single-mode optical fiber waveguide and superimposing the extracted portions to permit detection of a beat frequency therebetween. The beat frequency detected is indicative of the rate of angular rotation of the area circumscribed by the single-mode optical fiber waveguide. Means are provided to accommodate a significant reduction in the required laser pumping power.

摘要： A laser gyroscope for determining rotation of an area circumscribed by two closely adjacent optical fiber waveguides which serve as double laser cavities. Laser oscillation is restricted to one direction only in each optical fiber waveguide with the direction of oscillation in each waveguide being opposite to that in the adjacent optical fiber waveguide. Fractional parts of the laser radiation from the laser oscillation in each optical fiber waveguide are superimposed to develop a beat frequency therebetween which is proportional to the angular rotation of the area circumscribed by the two optical fiber waveguides.

摘要： An array of acoustic signal sources and sensors are positioned in a fluid. Acoustic signals propagated through the medium are subjected to phase differences as they pass through fluid currents. An eikonal description of the acoustic waves propagating through the fluid medium is used to derive the fluid currents. Fluid currents are measured in a multiplicity of acoustic paths extending from the acoustic sources to the sensors, using acoustic phase tomography.
