Claim 0:
1. A thermal radiation detection system, comprising:
a plurality of infrared sensor elements arranged as an array, wherein each of the plurality of infrared sensor elements comprises a semiconductor selected from a mercury-cadmium-telluride (HgCdTe)-based photodiode infrared detector, or an Indium Arsenide (InAs)-based photodiode infrared detector, configured to generate an output responsive to detected infrared wavelengths;
a temperature sensing circuit, the temperature sensing circuit configured to generate signals correlated to temperatures of one or more of the plurality of infrared sensor elements;
wherein the temperature sensing circuit comprises one or more temperature sensing device, wherein the one or more temperature sensing device is a negative temperature coefficient thermistor, a thermocouple, an infrared sensitive photodiode, or a resistance temperature detector; and
a signal processing circuit, the signal processing circuit configured to generate a signal usable by an imaging system based on the signals generated by the temperature sensing circuit and output based on the infrared sensor elements.
