利用纳米制造的电子全息图进行相位调制的最新进展已经展示了如何控制电子束的相位。在本文中，我们应用这一概念的扫描透射电子显微镜的球差校正，并证明了空间分辨率的改善。这种全息球面像差校正方法的优点在于其简单性和成本效益。
Recent progress in phase modulation using nanofabricated electron holograms has demonstrated how the phase of an electron beam can be controlled. In this paper, we apply this concept to the correction of spherical aberration in a scanning transmission electron microscope and demonstrate an improvement in spatial resolution. Such a holographic approach to spherical aberration correction is advantageous for its simplicity and cost-effectiveness.
