摘要:
An infrared camera system is provided to detect absorption of infrared radiation in a selected spectral bandwidth. In one example, an infrared camera system includes a lens adapted to receive infrared radiation from a survey scene comprising one or more gasses. The infrared camera system also includes a focal plane array comprising a plurality of quantum well infrared photo detectors (QWIPs). The QWIPs are tuned to detect a limited spectral bandwidth of the infrared radiation corresponding to at least a portion of an infrared absorption band of the one or more gasses. The infrared camera system also includes an optical band pass filter positioned substantially between the lens and the focal plane array. The optical band pass filter is adapted to filter the infrared radiation to a wavelength range substantially corresponding to the limited spectral bandwidth of the QWIPs before the infrared radiation is received by the focal plane array.

A non dispersive optical gas analyzer is disclosed which uses thermopiles as optical detectors. The thermopiles are formed of an array of interconnected thin films of dissimilar metals deposited on a heat conductive substrate to form a multitude of thermocouples. The array is configured in such a manner that a number of the thermocouples are employed to compensate each thermopile output signal for changes in ambient temperature.
