Iterative Phase Retrieval (PR) techniques represent an alternative means to Digital Holography (DH) for estimating the
complex amplitude of an optical wavefront. To achieve a high-resolution reconstruction from a digital hologram, one
must use Phase-Shifting Interferometric (PSI) techniques to remove the DC and twin image terms that are a feature of
holographic recordings. Unfortunately this approach is not suitable for imaging dynamic events, since a minimum of 3
sequential captures, are typically required and the scene cannot change during this recording process. PR algorithms
may provide a solution to this dynamic imaging problem, however these algorithms provide solutions that are not unique
and hence cannot ensure an accurate solution to the problem.
