Abstract
Complex object recovery from a digital hologram without the presence of dc or twin image terms is an extensively studied topic [1-2]. Recently we have demonstrated a novel computational method for high resolution image recovery from a single digital hologram of an amplitude object [8]. The complex object field is recovered from the hologram by solving a constrained optimization problem. This procedure is seen to overcome some of the current limitations on single shot digital holography. It can be shown that high quality image recovery is possible even when the dc and the cross terms in a hologram overlap in the Fourier domain. In this paper, through simulation, we intend to extend the work to the recovery of complex object information of pure phase objects.
