摘要： 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.

摘要： 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.

摘要： A thermal imaging system and method for quantitative thermal mapping of a scene. The system comprises a thermal imaging device, a heat source of known temperature and emissivity located within the scene viewed by the thermal imaging device and a processor adapted to generate a calibrated temperature map of the scene from the data supplied by the thermal imaging device, based on the known temperature of the heat source. This enables accurate temperature measurements to be made using inexpensive uncooled Focal Plane Array detectors.
