Reconstruction of Gas Densities from Multispectral Laser Measurements Using Method of Statistical Regularization

A problem of reconstruction gas densities from multispectral laser measurements is considered. Signal processing techniques, based on the method of statistical regularization of solutions of incorrect mathematical problems, is described for the laser method of differential absorption. Results of experimental investigations are given. The application of the statistical regularization method is shown to provide rather a low level of error of the gas density reconstruction.
