Abstract
To analyse Fabry-Perot interferograms, and to determine source profiles, two distinct methods of calculation by deconvolution were used. The first processing was based on the works of Duffieux (1939) and used Fourier analysis. Source functions and instrumental broadening functions were developed in Fourier's series and this method allowed the attainment of the source profile in its totality, if its function support was of finite value.
