Abstract

In this paper, we review the current state of phase plate imaging in a transmission electron microscope. We focus especially on the hole-free phase plate design, also referred to as the Volta phase plate. We discuss the implementation, operating principles and applications of phase plate imaging. We provide an imaging theory that accounts for inelastic scattering in both the sample and in the hole-free phase plate.

摘要

在本文中,我们回顾了透射电子显微镜中相板成像的现状。我们特别关注无孔相板设计,也称为伏打相板。我们讨论了相板成像的实现、工作原理和应用。我们提供了一种成像理论,该理论考虑了样品和无孔相板中的非弹性散射。
