Deep-Learning-Based Denoising for Improved Phase Precision in Electron Holography of Electromagnetic Fields in Nanoscale Materials. [PDF]

Adv Sci (Weinh)
Low‐dose electron holography is limited by shot noise, which buries weak phase signals. HoloDenoiser, a physics‐informed network that works simultaneously in the spatial and frequency domains, locates and protects the holographic sideband while suppressing noise in the hologram.
