Abstract
Techniques for calibrating differential temperature sources including the use of a calibrated infrared imaging sensor having an associated calibrated temperature function that is expressed as a function of a predetermined calculated parameter indicative of the actual differential temperature of a differential temperature source. The temperature source being calibrated is thermally imaged at different indicated differential temperatures to provide thermal images associated with the indicated temperatures, and such images are processed to define the calculated parameter as as function of indicated temperature. The calculated parameter function is substituted in the calibrated temperature function to provide a calibrated temperature function that is expressed as a function of indicated differential temperature.
