Filtering capabilities and convergence of the Van-Cittert deconvolution technique

The application of the Van-Cittert technique in iterative frequency-domain deconvolution is demonstrated. The technique is shown to have a built-in filtering capability which can successfully be used to produce optimum deconvolution estimates. The Bennia-Riad optimization criterion for iterative deconvolution is used with the Van-Cittert technique to optimize the number of iterations required to achieve acceptable (optimum) deconvolution results. An experimental example is provided to illustrate the application. of the deconvolution technique and the optimization criterion.<>
