Abstract

We present a digital holographic phase-unwrapping method based on comparison of phase images obtained by using various reconstruction distances. By utilizing information from multiple reconstruction planes, this method can effectively bypass the areas of phase noise. We demonstrate that this method performs better than the traditional phase-unwrapping approaches, even in the case of a complex topology where the data contains high levels of noise.
