Method of Bayesian estimates in the problem of laser gas analysis

The problem of reconstructing gas concentrations is considered for laser multicomponent gas analysis. For the differential absorption method, the procedures of signal processing are described based on the method of Bayesian estimates. It is demonstrated that the use of the method of Bayesian estimates the problem of reconstructing gas concentration both for few-and multicomponent gas mixtures allows to be solved effectively even for gases whose absorption spectrum has no noticeable maxima.
