title: Phase retrieval by propagation for localized images.
abstract: We present an algorithm for phase retrieval based on improvements to the methods developed by Bates [see Optik61, 247 (1982)]. Specifically, we have developed a more precise way of calculating phase differences between adjacent actual sampling points. This leads to a reduction in the error buildup in a recursive phase propagation scheme. Our approach has the advantage of having no adjustable parameters. We present a few examples of how this method can lead to improved image reconstructions.
