Fourier Synthetic Aperture-based Time-resolved Terahertz Imaging
Vivek Kumar, Pitambar Mukherjee, Lorenzo Valzania +3
Terahertz microscopy has attracted attention owing to distinctive characteristics of the THz frequency region, particularly non-ionizing photon energy, spectral fingerprint, and tr…
Single-pixel transmission matrix recovery via 2-photon fluorescence
Shupeng Zhao, Bernhard Rauer, Lorenzo Valzania +5
Imaging at depth in opaque materials has long been a challenge. Recently, wavefront shaping has enabled significant advance for deep imaging. Nevertheless, most non-invasive wavefr…
Three-dimensional operando optical imaging of single particle and electrolyte heterogeneities inside Li-ion batteries
Raj Pandya, Lorenzo Valzania, Florian Dorchies +10
Understanding (de)lithiation heterogeneities in battery materials is key to ensuring optimal electrochemical performance and developing better energy storage devices. However, this…
Phase Retrieval: From Computational Imaging to Machine Learning
Jonathan Dong, Lorenzo Valzania, Antoine Maillard +3
Phase retrieval consists in the recovery of a complex-valued signal from intensity-only measurements. As it pervades a broad variety of applications, many researchers have striven…
Accelerating ptychographic reconstructions using spectral initializations
Lorenzo Valzania, Jonathan Dong, Sylvain Gigan
Ptychography is a promising phase retrieval technique for label-free quantitative phase imaging. Recent advances in phase retrieval algorithms witnessed the development of spectral…
