Paper Abstract

In this work the stagnation problem in iterative single beam multiple intensity reconstruction algorithms is reduced by combining deterministic and iterative phase retrieval techniques in order to compensate for paraxial artifacts. This combined technique has a better convergence, because it suppresses better the stagnation problem present in iterative phase retrieval techniques. The reported hybrid deterministic-iterative phase retrieval techniques can be successfully employed for cases where an iterative solver is trapped in a local minimum, and moreover, allows increasing the convergence of iterative solvers.
