Tomographic reconstruction of composite small-screen in-line holograms

We generate and combine simulated holograms for low energy electron point source (LEEPS) microscopy. Using a relatively small screen size, we build a ``composite hologram'' from four different holograms, each obtained using the small screen. We show that reconstructions of high quality can be extracted from the composite hologram by implementing methods we developed in previous investigations. These high-quality reconstructions are obtained using a screen size that is one quarter the size of screens we have used previously. The implications of our results for experimental investigations is discussed. PACS No.: 61.14Nm
