Abstract: A novel phase unwrapping method with a hybrid of phase discontinuity marking, branch cut generation, and regional phase unwrapping is proposed. With this newly developed algorithm, quite noisy map coupled with real physical discontinuities can also be retrieved accurately and efficiently. A well-known simple wrapped map filter is used for filtering out most of the noise induced inconsistencies and leaving the phase discontinuities clearly shown on the map. The proposed algorithm is practically applied to an ESPI wrapped map for out-of-plane deformation detection. The practical unwrapping result reveals that the proposed method is effective for the phase unwrapping of ESPI work with real physical discontinuity.
