Abstract: A method and apparatus for detecting and removing water from a surface of a moving metal sheet in continuous treatment line to prevent the formation of water stains thereon. A selected surface area of the moving metal sheet is illuminated with infrared radiation having a wavelength substantially absorbed by water, and an optical sensor system is employed to view images reflected off the selected surface area. An optical bandpass filter limits transmission of infrared light to within a specific range of wavelengths known to be strongly absorbed by water. The sensor assembly produces a signal representative of the intensity of the reflected light. If the intensity signal is lower than a predetermined level, water is detected and the signal may be used to trigger a control device that sounds alarms, records the event, or otherwise controls the environment of the object so that detected water may be removed to prevent the formation of water stains.

Abstract: A radiation image that has been stored in photostimulable phosphor screen comprising a divalent europium activated cesium halide is read out by stimulating the phosphor screen by means of stimulating radiation, detecting light emitted by the phosphor screen upon stimulation and converting the detected light into a signal representation of said radiation image. After read out the phosphor screen is erased by exposing it to erasing light emitted by at least one electroluminescent lamp or by an array of light emitting diodes.

Abstract: A system for quantifying the petroleum content of aqueous media includes a sample cell; a first light source for generating a first light signal that stimulates fluorescent emissions when the first light signal irradiates hydrocarbons present in an aqueous solution in the sample cell; a spectral detector for generating a first electrical signal that represents spectral components of the fluorescent emissions in response to detecting the fluorescent emissions that are emitted from the sample cell; a second light source for generating a coherent light signal that is transformed into scattered light signals when the coherent light irradiates oil droplets in the aqueous solution; a detector for generating a second electrical signal in response to detecting scattered light signals emitted from the tube, where the second electrical signal represents the intensities and scatter angles of the scattered light signals; and a processor for determining a particle size distribution of the oil droplets from the second elec

Abstract: Crystal phase V2O3 with x=1.5 in VOx is prepared. Such a lower specific resistance than a desired one as a starting film quality is modified to the final desired specific resistance by heating under an oxidizing atmosphere. A protective film for a bolometer material is formed by physical vapor deposition.

Abstract: An infrared photodetector focal plane array includes large dynamic range Read Out Integrated Circuits. Increased dynamic ranges are achieved in each ROIC of the array using switched capacitor filter arrangements that include a single “cup” capacitor and at least two “bucket” capacitors. Dynamic range is improved by controlling the ratio of the current to voltage transfer resistance gains between the “cup” capacitor and each “bucket” capacitor of the filter. With an increased dynamic range, the switched capacitor filter arrangement allows the focal plane array to adequately resolve the infrared radiation received from both hot and cold objects.

Abstract: In a radiation image read-out apparatus, a stimulable phosphor sheet storing thereon a radiation image is exposed to stimulating light and stimulated emission emitted from the stimulable phosphor sheet upon stimulation by the stimulating light is detected and an image signal representing the radiation image stored on the stimulable phosphor sheet is obtained by photoelectrically converting the stimulated emission. A read-out system includes an array of a plurality of read-out heads, each including a stimulating light source which projects the stimulating light onto the stimulable phosphor sheet and a photodetector which detects the stimulated emission. A conveyor system conveys the stimulable phosphor sheet and the read-out system relative to each other in a direction intersecting the direction of the array of the read-out heads.

Abstract: The present invention is directed to an uncooled, infrared detector which includes a sensor having an amorphous surface layer containing organic carbon and a high dopant concentration which possesses an improved temperature coefficient of resistivity, as well as improved responsivity, and which may be patterned to form a focal plane array by means of common microlithographic techniques. The present invention is additionally directed to an “ion beam mixing” process for preparing the present infrared sensor.
