Abstract: The invention relates to a passive microbolometer (12), comprising a reflective screen (17) and a suspended membrane with the function of radiation absorber, thermometer and electrical connection. The membrane is supported by at least two anchor elements (15) fixed to a support substrate (16). The reflective screen (17) may be embodied by at least one layer (18) of metallic material with a thickness of the order of 500 Å to 2000 Å. The screen (17) is arranged beneath the membrane in electrical contact with the membrane absorber element (13) such as to reduce the area resistance of the unit made up of the screen (17) and the absorbing element (13) and to avoid the absorption of radiation by the latter.

Abstract: Method and device for direct, non-contact temperature measure of a body. A laser beam is reflected from the surface of the body and detected along with the Planck radiation. The detected signal is analyzed using signal correlation technique to generate an output signal proportional to the Johnson noise introduced into the reflected laser beam as a direct measure of the absolute temperature of the body.

Abstract: A method and apparatus for measuring the absorptivity of a radiation detector by making the detector an integral part of a cavity radiometer. By substituting the detector for the surface of the cavity upon which the radiation first impinges a comparison is made between the quantity of radiation incident upon the detector and the quantity reflected from the detector. The difference between the two is a measurement of the amount of radiation absorbed by the detector.

Abstract: In a thermal imaging system and method of using the thermal imaging system, a piezoelectric actuator is disposed between a thermal sensor and a readout circuit. Total radiance in the scene is detected with the thermal sensor and background radiance in the scene is detected by movement of at least a portion of the piezoelectric actuator between the thermal sensor and the readout circuit. The detected background radiance is subtracted from the detected total radiance to provide a signal representing the actual radiance of an object in a scene.

Abstract: A system for locating inflamed plaque in an artery of a patient includes a catheter with an expander mounted at a catheter distal end. An infrared carrier, e.g., an optical fiber is mounted on the catheter with a carrier distal end attached to the expander. A sensor is connected to a carrier proximal end to measure infrared radiation transmitted through the carrier from the carrier distal end. In use, the expander is operable to selectively move the carrier distal end into contact with the arterial wall. Infrared radiation can then be measured to determine the temperature at the arterial wall. Temperatures at various locations can be taken, with elevated temperatures being indicative of inflamed plaque.
