衍射图案包含有关材料的有用信息。四维扫描透射电子显微镜和衍射图空间分布采集的最新发展已经产生了重要的结果。对静止光束实现了时间序列衍射的采集。然而，衍射图时空分布的获取仅在有限的条件下建立。在这项研究中，我们开发了一种简单的方法，可以记录衍射图案的时空分布，并将其应用于对样品漂移具有鲁棒性的弛豫时间测量。
Diffraction patterns contain useful information about the materials. Recent developments in four-dimensional scanning transmission electron microscopy and the acquisition of the spatial distribution of diffraction patterns have produced significant results. The acquisition of a temporal series of diffractions is achieved for a stationary beam. However, the acquisition of spatiotemporal distribution of diffraction patterns has only been established under limited conditions. In this study, we developed a simple method that enables the recording of the spatiotemporal distribution of diffraction patterns and applied it to the relaxation time measurement that is robust to sample drift.
