Description
Summary:The concept, design and present stage of development of a new type of electrooptical gas sensor system, with application to the simultaneous detection of several atmospheric pollutant gases, is described. The sensor system is based on non-dispersive infrared differential optical absorption spectroscopy. Spectral analysis is performed by a sensor device with no moving parts, consisting of an array of integrated bandpass multilayer filters coupled to an array of PbSe detectors. The principle of detection has been demonstrated for concentrations in the range of a few ppm.
