Abstract:
Le système radiométrique isothermique amélioré est du type à double jonction (de préférence cuivre-constantan-cuivre) et comprend un logement d'un corps noir (B1) définissant une concavité centrale. La concavité centrale possède un disque du corps noir (D1) au fond de la concavité. De préférence, le disque est suspendu par un fil de cuivre (14) et de constantan (16) avec une jonction (32) formée sur la surface du disque et l'autre jonction (34) formée sur la surface du logement. L'amélioration consiste en une pluralité de chicanes annulaires, de préférence trois chicanes annulaires (50, 52, 54) définissant une ouverture centrale, circulaire et de préférence concentrique. Ces chicanes sont logées dans l'ouverture (30) du logement au-dessus du disque radiométrique (D1). Les chicanes annulaires, sur le côté dirigé vers la source de rayonnement, sont revêtues comme un corps noir de manière à augmenter le couplage thermique du logement du corps noir avec l'environnement observé par radiométrie. Les chicanes, en éloignement par rapport à la source de rayonnement et exposées au disque radiométriques, sont revêtues de manière réfléchissante pour diminuer davantage tout couple entre le disque radiométrique et le logement du corps noir. La combinaison des chicanes et du disque donne au radiomètre un petit champ de vision qui permet la mesure thermique radiométrique d'un petit angle plein et ignore le reste de l'environnement. Une utilisation préférée du radiomètre sur un rotor (R1) d'une centrifugeuse est décrite.
Abstract:
Systems and methods are provided for generating isothermally enhanced images. An isothermally enhanced image may be an isothermally enhanced non-thermal image such as an isothermally enhanced visible light image. An isothermally enhanced visible light image may include a visible light image portion and a thermal image portion. The thermal image portion may be a portion of the image having temperature-related pixel values. The portion of the image may correspond to an image of an object or objects having temperatures within a particular temperature range. In this way, an isothermally enhanced visible light image may be provided that has visible light image resolution for scene and object identification and recognition and has temperature information for objects having temperatures of interest such as particularly hot objects or particularly cold objects. The temperature information in may be presented using colors each corresponding to isothermal portions of the image.
Abstract:
The isothermal radiometric system improved is of the double junction variety (preferably copper-constantan-copper) and includes a black body housing (B1) defining a central concavity. The central concavity has a black body disk (D1) at the bottom thereof. The disk is preferably suspended by a copper (14) and a constantan (16) wire with one junction (32) formed on the surface of the disk and the other junction (34) formed on the surface of the housing. The improvement includes a plurality of and preferably three annular baffles (50, 52, 54) defining central, circular and preferably concentric opening. These baffles are lodged in the opening (30) of the housing above the mounted radiometer disk (D1). The annular baffles on the side towards the radiation source are coated as a black body so as to increase the thermal coupling of the black body housing to the ambient being radiometrically observed. The baffles on the side away from the radiation source and exposed to the radiometer disk are reflectively coated to decrease further any couple between the radiometer disk and the black body housing. The combination of the baffles and the disk combine to give the radiometer a small field of view which permits radiometric thermal measurement of a small solid angle and ignores the remainder of the environment. Preferred use of the radiometer in looking at a centrifuge rotor (R1) is disclosed.
Abstract:
A system for detecting a temperature of a railroad train wheel or bearing includes a thermal line scanner and a processor. The thermal line scanner is positioned to capture a plurality of thermal line scans of the wheel or bearing. The processor is configured to analyze each of the plurality of thermal line scans, identify a selected line of the plurality of thermal line scans, and calculate the temperature of the wheel or the bearing based on the selected line. Thus, the system and method disclosed herein reduce the acquired thermal data first to a single line for one or both of the wheel temperature and bearing temperature and then to single values.
Abstract:
The present disclosure is directed to a method for detecting a condition associated with a wheel on a train car. The method may include detecting a position of the wheel. The method may also include detecting a position of a rail on which the wheel travels. The method may further include comparing the position of the wheel relative to the position of the rail, and determining a wheel condition based on the comparison.
Abstract:
An improved system for evaluating one or more components of a vehicle is provided. The system includes a set of imaging devices configured to acquire image data based on infrared emissions of at least one vehicle component of the vehicle as it moves through a field of view of at least one of the set of imaging devices. An imaging device in the set of imaging devices can include a linear array of photoconductor infrared detectors and a thermoelectric cooler for maintaining an operating temperature of the linear array of detectors at a target operating temperature. The infrared emissions can be within at least one of: the mid-wavelength infrared (MWIR) radiation spectrum or the long wavelength infrared (LWIR) radiation spectrum.
