Accelerated deep self-supervised ptycho-laminography for three-dimensional nanoscale imaging of integrated circuits

1 code implementation10 Apr 2023 Iksung Kang, Yi Jiang, Mirko Holler, Manuel Guizar-Sicairos, A. F. J. Levi, Jeffrey Klug, Stefan Vogt, George Barbastathis

Two scanning operations are required: ptychographic to recover the complex transmissivity of the specimen; and rotation of the specimen to acquire multiple projections covering the 3D spatial frequency domain.

Attentional Ptycho-Tomography (APT) for three-dimensional nanoscale X-ray imaging with minimal data acquisition and computation time

1 code implementation29 Nov 2022 Iksung Kang, Ziling Wu, Yi Jiang, YuDong Yao, Junjing Deng, Jeffrey Klug, Stefan Vogt, George Barbastathis

Noninvasive X-ray imaging of nanoscale three-dimensional objects, e. g. integrated circuits (ICs), generally requires two types of scanning: ptychographic, which is translational and returns estimates of complex electromagnetic field through ICs; and tomographic scanning, which collects complex field projections from multiple angles.
