Title Two-dimensional Phase Unwrapping for Digital Holography.
Publication Date Sep 2012

Abstract This work describes a method for eliminating the mathematical ambiguity in the phase map for digital holographic images. The technique uses a pre-processing step to smooth the amplitude data and reduce noise in the phase data. The unwrapping algorithm uses both phase gradient calculations and an amplitude measure to determine the reliability of a given data point, and uses a non-continuous path following approach.
