Method of Bayesian Estimations in Problem of Laser Gas Analysis

A problem of determination of gas concentrations from multispectral laser measurements is considered. Procedures of signal processing based on a method of Bayesian estimations of the solution to the system of equations of laser gas analysis are described. It is shown that the application of the method of Bayesian solution estimations provides the fairly low level of errors of the gas concentration determination even with substantial measurement noise and distorted matrix of absorption factors.
