A Two-Path Method for Eliminating the Effects of Self-Absorption on Temperature for Isothermal Flames

Penner, S. S.


It is the purpose of the current note to outline a two-path method for the determination of flame temperatures. The method is valid for isothermal systems and spectral lines with Doppler contour. All errors arising from self-absorption are eliminated. Practical applications are made by determining the ratio of the total intensity observed when the flame is viewed with a cool blackbody as background to the total intensity obtained with a cool mirror as background.
