  • Publication number: 20220236173
    Abstract: An optical gas concentration measurement apparatus is disclosed. The optical gas concentration measurement apparatus includes a thermally insulated enclosure that has a gas sample cell situated within. A thermally-insulating, light-guiding element passes through an access port of the thermally insulated enclosure and is configured to direct light from a light source outside of the thermally insulated enclosure to the gas sample cell. A light detector outside of the thermally insulated enclosure is optically coupled to the gas sample cell and an electronic assembly outside of the thermally insulated enclosure is configured to receive information from the light detector.

  • Patent number: 9255846
    Abstract: A method, system, and non-transitory computer readable medium storing a plurality of computer executable instructions for calibrating an uncalibrated thermal imager is provided. The system includes a calibrated pyrometer for determining a first temperature of a Region of Interest under a first condition, and an uncalibrated thermal imager for determining a first average count value over the region of interest under the first condition and for determining a second average count value over the region of interest under a second condition. A temperature sensor for determining a second temperature of the region of interest under a second condition is also provided. Control electronics determine a Planck function that intersects the points (first temperature, first average count value) and (second temperature, second average count value). The uncalibrated thermal imager is calibrated using the Planck function.

  • Patent number: 8450686
    Abstract: A thermal imaging system to facilitate analysis of thermal images comprises a portable thermal imager having a communication interface for transfer of data. The imager also has an on-board memory in which image data for corresponding thermal images is stored. A remote computer is operative to communicate with the thermal imager via the communication interface for download of the image data. The computer runs software operative to superimpose at least one marker at a selected location on a thermal image, the marker being saved on the image.

  • Publication number: 20080308732
    Abstract: A graphical user interface for analyzing thermal images is provided. The interface can be used to identify the temperatures at multiple areas of interest defined on an image. The areas can be denoted by configurable markers of different predetermined shapes. In some embodiments, the interface simultaneously displays temperature statistics relating to the user-identified areas of interest.
