在扫描透射电子显微镜（STEM）中收集的实验数据用于获得由物镜孔径的大小确定的常规分辨率的两倍的样品的图像。测量的数据还提供了一个强大的重建质量的估计，确定这样的变量，如样本漂移，散焦的物镜透镜，源相干性和机械不稳定性。
Experimental data collected in a scanning transmission electron microscope (STEM) is used to obtain an image of the specimen at twice the conventional resolution determined by the size of the objective aperture. The measured data also provide a robust estimate of the quality of the reconstruction, determining such variables as specimen drift, defocus in the objective lens, source coherence and mechanical instability.
