Deep-Learning Electron Diffractive Imaging

|
By Dillan J. Chang, Colum M. O’Leary, Cong Su, Daniel Jacobs
| Physical Review B
Abstract We report the development of deep-learning coherent electron diffractive imaging at subangstrom resolution using convolutional neural networks (CNNs) trained with only simulated data. We experimentally demonstrate this method by applying the trained CNNs to recover the phase images from electron diffraction patterns of twisted hexagonal boron nitride, monolayer graphene, and a gold nanoparticle with comparable quality to those reconstructed by a conventional ptychographic algorithm.
