Thermography (thermal imaging)Thermography, or thermal imaging, involves scanning aninfrared radiation detectoracross an object. The information gathered is then processedand an output in the formof the temperature distribution across the object is produced.Temperature measurementover the range from -20C up to +1500C is possible.The radiation detector uses the same principles of operation asa radiation pyrometerin inferring the temperature of the point that the instrumentis focused on froma measurement of the incoming infrared radiation. However,instead of providing ameasurement of the temperature of a single point at the focalpoint of the instrument,the detector is scanned across a body or scene, and thusprovides information abouttemperature distributions. Because of the scanning mode ofoperation of the instrument,radiation detectors with a very fast response are
