We report a method for quantitative phase recovery and simultaneous electron energy loss spectroscopy analysis using ptychographic reconstruction of a data set of "hollow" diffraction patterns. This has the potential for recovering both structural and chemical information at atomic resolution with a new generation of detectors.
我们报告了一种使用“空心”衍射图样数据集的相衬重建进行定量相位恢复和同时电子能量损失谱分析的方法。这种方法有可能利用新一代探测器以原子分辨率恢复结构和化学信息。
