Journal ArticleDOI
Oversampling smoothness: an effective algorithm for phase retrieval of noisy diffraction intensities
TL;DR: Both numerical simulations with Poisson noise and experimental data from a biological cell indicate that OSS consistently outperforms the HIO, ER-HIO and noise robust (NR)-HIO algorithms at all noise levels in terms of accuracy and consistency of the reconstructions.
Journal ArticleDOI

TL;DR: The experimental demonstration of single-shot 3D structure determination of an object; in this case, individual gold nanocrystals at ~5.5 nm resolution using ~10 fs X-ray free-electron laser pulses.
Journal ArticleDOI
Oversampling smoothness (OSS): an effective algorithm for phase retrieval of noisy diffraction intensities
TL;DR: In this article, an effective iterative algorithm, termed oversampling smoothness (OSS), was proposed for phase retrieval of noisy diffraction intensities, which exploits the correlation information among the pixels or voxels in the region outside of a support in real space.
