Two object-dependent filters (an amplitude and a phase filter) are used in the object plane on the iterative calculation of a kinoform instead of a single (phase) filter as usual. The amplitude filter is a system of weight coefficients that vary in the process of iterations and control the amplitude of an input object. The advantages of the proposed method over other ones are confirmed by computer-based experiments. It is found that the method is most efficient for binary objects.
