    Abstract: A thermal imaging system includes a mounting structure characterized by a first thermal conductivity and a focal plane array mounted to the mounting structure. The thermal imaging system also includes an optical system coupled to the mounting structure and a heating element coupled to the mounting structure. The thermal imaging system further includes a thermal isolator coupled to the mounting structure and characterized by a second thermal conductivity lower than the first thermal conductivity.

    Abstract: An extended area “cavity type” blackbody for use as a radiometric reference for imaging systems may have a well in the form of a cube having four sidewalls and a back wall, and open at the front. The temperature of the back wall may be controlled independently of the temperature(s) of the sidewalls. This system may produce infrared radiance closer to an ideal radiator than typical extended area sources. A “simple” blackbody is disclosed, having a source plate with a front emitting surface; a ledge element disposed in front of and below the source plate for heating air in front of the source plate; and (optionally) another ledge element disposed in front of and above the source plate for cooling air in front of the source plate. A housing may support the source plate and ledge element, and a vent may be provided in front of and above the source plate. A resistive heater may be associated with the ledge element; and (optionally) TECs may be associated with the other (cooling) ledge element. Angles of the ledges may be adjustable to optimize the best uniformity for a particular implementation. Temperature control of the ledges may be in unison with or independent from the source plate.

    Abstract: Disclosed is an integrated circuit (IC) chip incorporating a temperature-sensitive element and temperature stabilization circuitry for ensuring that the temperature of the temperature-sensitive element (TSE) remains essentially constant. The IC chip comprises a temperature-sensitive element and, within at least one region adjacent to the temperature-sensitive element, a first circuit that radiates a first heat amount to the TSE and a second circuit that radiates a second heat amount to the TSE. The second circuit senses changes in a first current amount in the first circuit and, thereby changes in the first heat amount. In response to those changes, the second circuit also automatically adjusts a second current amount in the second circuit and, thereby the second heat amount in order to ensure that the total heat amount radiated by the first circuit and the second circuit, in combination, to the TSE remains constant. Also disclosed is an associated method.
