This study determines a means of processing experimental data using a non-ideal Fabry-Perot interferometer. Using such an instrument, one can ignore distortion induced by the instrument profile in the results of measuring the concentration of atoms. With a priori information (e.g., on the ratio of the gas temperatures for the test and illuminating discharges) the procedure of processing is substantially simplified, and one obtains simple equations for determining the concentrations of atoms in a metal. The effectiveness of this method is analyzed through an example in determining the concentration of atoms in a metal with a discharge in a hollow cathode. As a control for the experiment, the concentration is simultaneously determined by a spectral-sounding technique.
