APPLICATION OF A DECONVOLUTION METHOD TO PLASMA EMITTED SPECTRA

A non-linear deconvolution method called Biraud's method is presented. Using shapes of positive spectra, performances and limits are tested by numerical experiments. Results show that this treatment is adapted to restore noisy spectral line parameters with most apparatus functions. Comparing with other non-linear methods, we find an improvement on reconstructed profiles. Application to plasma emitted spectra leads to accurate line parameters restoration even with significant noise levels.
