abstract

The aim of this communication is to show how the Richardson-Lucy deconvolution algorithm can be applied to the blind deconvolution problem. After a brief description of the R.L algorithm itself, we start from the basic papers of Ayers and Dainty (1988) and Lane (1992) and introduce in their approach the R.L algorithm in several different ways. We show that the general behaviour of the proposed methods is analogous to that of the error-reduction algorithms and that good solutions can be obtained. The unregularized behaviour of the RL algorithm is overcame by a limitation of the iteration number. Moreover we compare the structures of the various algorithms proposed here and emphasise the main differences. The proposed algorithms are used to blindly deconvolve two types of objects (point-like and extended objects) blurred by simulated point spread functions similar to those observed at the focus of a small telescope in presence of at- mospheric turbulence. The error reduction term is given as a function of the iteration number.
