Abstract
We investigate phase imaging from a diffraction pattern in the presence of vortices. In particular we demonstrate that a difference map method for phase retrieval which contains a support constraint does not necessarily conserve the net topological charge of the trial wave field. Hence, no a priori information regarding the charges of the vortices is required for a successful phase retrieval.
