The design of a stationary absorption gas analyzer, employing a broadband IR radiation source, an interference filter, and a Fabry-Perot interferometer, is considered. The gas analyzer is intended for measuring the concentration of CO molecules in effluent gases of heat and power plants. The optimal optical parameters of the interference filter and Fabry-Perot interferometer are calculated. It is shown that with the optimal parameters of the filter and interferometer the differential absorption signal increases by 50 to 100 times in comparison with the standard scheme of formation of the differential absorption signal without a Fabry-Perot interferometer.
