Paper Abstract

Both thereconstructed imagebandwidth which islimited by the finite sizeofthehologram and twin image artifactcaused by the lack ofphase information restrict the achievable reconstruction resolution using in-line holography. In this paper an new iterative error energy reduction algorithm is used to address these problems. This algorithm suggests the possibility of superresolution in in-line holography in which the conventional diffraction limit may be approached or even exceeded. Superresolution has been demonstrated for several other types of coherent and incoherent imaging but not yet for holography. 1 .
