Abstract:

The interferometric solar image reconstruction is the last and the most important method to get the highresolution image.The Skilling-Bryan maximum entropy method featured in convergence rate is one of the predominant methods in astronomy image proceeding.The proposed method innovated in search directions of SB combines the speed with exactness harmoniously as a result of the error adjustment.Finally the simulations were conducted with both methods of interferometric solar image reconstruction in national astronomical observatories.Results showed the superiority of the improved method in resolution and counterbalance in computing time.Its stability was also testified with various examples.

Key words: interferometer, maximum entropy method, deconvolut ion, image reconstruction
