Experience with Measuring of the Spectral Line Profile by Means of the Fabry-Perot Interferometer

Results of plasma diagnostics by means of the Fabry‐Perot interferometer are very sensitive to a right adjustment, a choice of both the working diaphragm and exposition time, etc. Furthermore, a choice of adequate methods applied to the calculation of plasma parameters from experimental data is very important. As it is very difficult to verify the validity of measured results in this case, a sufficient attention was not given to these problems and at present we find only few really useful information in literature, which would correspond with conterporary level of technique. In this paper there is summarized our experience obtained during many years use of the Fabry‐Perot interferometer in plasma diagnostics.
