ABSTRACT:
A sensor includes two thermal energy detectors thermally insulated from one another. The first detector is warmed or cooled by radiation between it and the object being measured. The second detector is warmed or cooled by exchange of thermal energy with a thermal reference source until the second detector reaches a temperature that is a predetermined ratio with that of the first detector. A control circuit which receives signals from the detectors that represent their temperatures, provides control for the thermal reference. A third detector measures the temperature of the thermal reference source and provides a signal representative of the temperature of the reference source. A processor receives the signal from the third detector and provides a signal indicative of the temperature of the object.
