A simple algorithm for spectral line deconvolution

The objective of this work is to develop a numerical procedure to subtract the instrumental function from a measured spectral line profile. The measur ing device (for example, a Fabry-Perot Interferometer) distorts the spectra l line profile and the experimentally measured one is a convolution of this profile and the instrumental function. Restoring the spectral line profile is strongly affected by numerical instabilities and the problem has been o vercome by using the Tikhonov regularization method. The approach is very s imple and easy for programming and it is particularly useful for "noisy" ex perimental data. (C) 2001 Elsevier Science Ltd. All rights reserved.
