Electron holography was invented for correcting aberrations of the lenses of electron microscopes. It was used to observe the atomic arrangements in crystals after decades of research. Then it was combined with a hardware aberration corrector to enable high-resolution and high-precision analysis. Its applications were further extended to magnetic observations with sub-nanometer resolution. High-resolution electron holography has become a powerful technique for observing electromagnetic distributions in functional materials.

全息：高分辨率成像的应用

电子全息术是为了校正电子显微镜透镜的像差而发明的。经过几十年的研究，它被用来观察晶体中的原子排列。然后结合硬件像差校正器，实现高分辨率和高精度分析。它的应用进一步扩展到亚纳米分辨率的磁观测。高分辨率电子全息术已成为观察功能材料中电磁分布的强大技术。
