This work is devoted to an elimination of the phase discontinuities problem of the
reconstructed object wavefront. Novel robust phase unwrapping method is proposed. It is based
on the phase shift implementation of the reconstructed wavefront. The unwrapped phase eld
of the amplitude-phase object is presented. Comparison with another known methods is shown
and discussed. Proposed method resistant to noise and object phase eld inhomogeneities. Its
advantages are robustness and simplicity
