【 摘 要 】

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 field of the amplitude-phase object is presented. Comparison with another known methods is shown and discussed. Proposed method resistant to noise and object phase field inhomogeneities. Its advantages are robustness and simplicity.
