Temperature Distribution Measurement in an Axially Symmetric Source which is not Optically Thin

We elaborated two spectroscopic methods for the temperature distribution in axially symmetric source. One method uses the self-reversed spectral line ; this method is based on a comparison of the measured absolute maximum (peak) intensity with that calculated as a function of axial temperature. Another method which uses a spectral line without self-reversal, was based on the Kirchhoff's law and exploits two-path absorption technique and Abel transformation. For both methods, knowledge of atomic broadening constants and transition probabilities is not crucial.
