摘要： A particular area or areas are monitored for the presence of gaseous materials, particularly pollutants by analyzing background infrared radiation present in the selected area with a spectrometer and making the results of this analysis available in a form understandable to the person or device monitoring the area for the presence of specified gaseous materials. The results of the spectrometric analysis may, for example, be displayed on a video unit or they may be printed. Apparatus useful in the practice of this invention generally includes an interferometer of the Michaelson-Morely type having specific optical characteristics, a sensitive infrared detector, electronic data processor, and a device which records and/or displays the results of the determination(s). In a preferred embodiment, no radiation concentrating or focusing elements are used ahead of the beamsplitter of the Michelson-Morely interferometer, said interferometer having imaging optics which, combined with detector size, results in the optical field of view being essentially no larger than the area of the remote source employed.

摘要： A method and apparatus are described for monitoring an area or areas for the presence of gaseous materials, particularly pollutants, by collecting and analyzing infrared radiation present in the selected area, wherein the apparatus contains a computer controlled platform which positions a reflective surface in azimuth and elevation to direct said radiation into an interferometer for analysis. The results of the spectrometric analyses are made available in a form understandable to the person or device monitoring the area for the presence of specified materials. The results of the spectrometric analysis may, for example, be displayed on a video unit, printed or used to sound an alarm.

摘要： A particular area or areas are monitored for the presence of gaseous materials, particularly pollutants by collecting background radiation (both visible and infrared radiation) present in the selected area, analyzing the radiation collected with a spectrometer and making the results of this analysis available in a form understandable to the person or device monitoring the area for the presence of specified gaseous materials. The results of the spectrometric analysis may, for example, be displayed on a video unit or they may be printed. In a preferred embodiment, the results of the spectrometric analysis are displayed on a video unit simultaneously or sequentially with the image of the area from which the background radiation had been collected. Apparatus useful in the practice of this invention generally includes large energy collecting mirrors, an interferometer of the Michaelson-Morely type, a sensitive infrared detector, electronic data processing, and a device which records and/or displays the results of the determination(s). In a preferred apparatus, a "hot" mirror, a video camera, a computer and a video display unit are also employed.
