Abstract
A method is developed for processing the results of measuring gain or absorption by multiple sounding of gaseous media. The accuracy of the determined parameters of gaseous media is analyzed as a function of the accuracy with which the gain or absorption is measured. The method was developed by solving model problems and used to reduce the measured values of the gain in media containing CO and CO2 molecules. Recommendations are made for diagnostics of equilibrium and nonequilibrium gaseous media containing CO and CO2 and conditions are stipulated with respect to the probing system and the measurement accuracy needed in measurements of the gain and absorption indices from which the parameters of the gaseous media are determined.
