A software package for the processing and reconstruction of electron holograms

SUMMARY Electron holography is leaving its state of infancy and is rapidly becoming a tool for everyday use. This is due to the increasing availability of field-emission electron microscopes as well as the increasing use of slow-scan CCD cameras, which provide the linear image recording so essential to electron holography. At the same time, the continuing boost in performance of desktop computers both in hardware and in software has facilitated the handling of many of the complex reconstruction and processing tasks of electron holography. We describe here the software package ‘HoloWorks©’, recently developed at Oak Ridge National Laboratories. This package is designed for the processing of electron holograms stressing easy-to-use functions and is a plug-in module for Gatan's software DigitalMicrograph®.
