Information limit of 15 picometers achieved with bright-field ptychography

H Sha, J Cui, W Yang, R Yu - Physical Review B, 2024 - APS
It is generally assumed that a high spatial resolution of a microscope requires a large
numerical aperture of the imaging lens or detector. In this study, the information limit of 15 …
