Video-rate holographic telepresence via single-shot, reference-free wavefront measurement
Minwook Kim, Chansuk Park, Chulmin Oh +3
We present a reference-free holographic telepresence system that directly captures and replays complex optical wavefronts from a single intensity speckle measurement. Using a pre-c…

Speckle-based X-ray microtomography via preconditioned Wirtinger flow
KyeoReh Lee, Herve Hugonnet, Jae-Hong Lim +1
Quantitative phase imaging has been extensively studied in X-ray microtomography to improve the sensitivity and specificity of measurements, especially for low atomic number materi…

Quantitative X-ray Schlieren Nanotomography for Hyperspectral Phase and Absorption Imaging
Herve Hugonne, KyeoReh Lee, Sugeun Jo +2
Hyperspectral X-rays imaging holds promise for three-dimensional (3D) chemical analysis but remains limited in simultaneously capturing phase and absorption information due to comp…
