Unfolding wrapped phase

Paper Abstract

Phase unwrapping is the final step in phase extraction methods, which consists of recovering the correct phase from the wrapped phase by removing discontinuities. The difference between the correct phase and the wrapped phase is the phase wrapping map. A new method for phase unwrapping is presented by identifying the phase wrapping map as a sequence of binary valued intermediate wrapping maps and iteratively removing them producing the correct phase by phase-wrapped unfolding. A path-following algorithm is presented to exemplify the phase wrapped unfolding method.
