Abstract: A cooling type infrared rays detecting apparatus is disclosed which prevents a fluctuation of an infrared rays image arising from a variation of the cooling temperature. The infrared rays detecting apparatus includes a dummy element mounted adjacent an infrared rays detecting device on a device mounting portion of an inner tube. The dummy element has a similar structure to that of each of infrared rays detecting elements of the infrared rays detecting device and is formed from the same material as the latter. A temperature variation of the dummy element is detected from a variation in resistance of the dummy element, and an output of the infrared rays detecting device is compensated for in response to the thus detected temperature variation to prevent a possible fluctuation of an infrared rays image arising from a temperature variation. Consequently, an infrared rays image of a high quality can be obtained.

Abstract: A detector assembly includes a dewar chamber having an aperture and an infrared radiation detector. The detector assembly also includes a mirror disposed adjacent the aperture of the dewar chamber, where the mirror has a reflective surface and an emitting region facing the aperture. The infrared radiation detector is configured to detect first radiation and second radiation from the mirror. The first radiation originates from at least one relatively cold surface in the dewar chamber and reflects off the reflective surface of the mirror. The second warm radiation originates from at least one relatively warm surface at or behind the emitting region. The infrared radiation detector is also configured to detect an artifact caused by a particle in the dewar chamber that blocks a portion of the first or second radiation.

Abstract: A measuring apparatus comprises a detector device for detecting a variable to be measured, and a controller operative to control the detector device and generate an output signal indicative of the magnitude of the variable being measured. The detector device comprises a housing on which are mounted two Peltier-Seebeck detectors, the detectors being arranged on the housing such that only the first Peltier-Seebeck detector is exposed, in use, to the variable to be measured. The controller is operative to generate the output signal based on the output of the first Peltier-Seebeck detector and the output of the second Peltier-Seebeck detector so as to account for the effect of the ambient heat on each Peltier-Seebeck detector.
