  • Method and apparatus for measuring the temperature of a sheet material
    Patent number: 8536514
    Abstract: A method of measuring the temperature of a sheet material in which the sheet material is arranged such that it forms at least one side of a cavity so as to enhance the effective emissivity of the sheet material in the vicinity of the cavity.
    Type: Grant
    Filed: July 30, 2010
    Date of Patent: September 17, 2013
    Assignee: Land Instruments International Limited
    Inventors: Thomas Geoffrey Ronald Beynon, Ian Hamilton Ridley, Stuart Francis Metcalfe, Andrew Mellor, Ben Wileman
  • Radiation thermometer
    Patent number: 8042997
    Abstract: A radiation thermometer comprising a radiation detector and an optical input path arranged to direct radiation from an object of interest to the radiation detector is disclosed. The radiation detector is adapted to output a signal related to the radiation received from the object of interest, and a processor is adapted to generate temperature measurements from the signal. Filtering means are provided in the optical input path which are arranged to block radiation having a wavelength between approximately 0.92 and 0.98 microns.

  • Real-Time Line Scan Extraction from Infrared Images Using the Wedge Method in Industrial Environments
    Publication number: 20090196324
    Abstract: A method of measuring the temperature of a sheet material arranged such that it forms at least one side of a cavity, so as to enhance the effective emissivity of the sheet material in the vicinity of the cavity comprises: generating a thermal image of at least part of the inside of the cavity, the thermal image comprising a plurality of pixels each having a pixel value representative of radiation emitted by a respective region of the cavity; identifying a first subset of the pixels whose pixel values meet predetermined criteria; using the identified first subset to determine a line on the thermal image representative of optimal emissivity enhancement in the cavity; and selecting a second subset of the pixels based on the determined line and generating a temperature profile along the determined line derived from the pixel values associated with each of the second subset of pixels.
