Paper Abstract

The development of effective methods in environmental pollution control is a main task of environmental research. Fourier-transform IR spectroscopy is an efficient technique for the detection and quantification of molecules in gas mixtures. A passive IR system designed to detect specific pollution clouds in the atmosphere and sound an alarm in time. The sensor is a Fourier transform spectrometer operating in the 8-12 micrometers atmosphere window region of the spectrum. The system can be operated unattended and be highly reliable and accurate in its decisions. An on-board microcomputer will be applied to achieve automatically control of system, acquire data, process it and make decisions. The paper describes the signal processing and spectral pattern recognition techniques. Measurement results for ambient air with the spectrometer are reported.
