Gigavoxel-scale multiple-scattering-aware lensless holotomography

Mikołaj Rogalski, Julianna Winnik, Julia Dudek, Piotr Arcab et autres

Abstract Holotomography (HT) has revolutionized quantitative label-free 3D imaging, yet conventional lens-based implementations are fundamentally constrained in field-of-view (FOV) and imaging depth, limiting their utility for critical high-throughput applications in material and life sciences. Lensless HT (LHT) offers a promising alternative for …

YOSO: single-frame Gerchberg–Saxton phase retrieval with AI-based data augmentation for in-line holography

Julianna Winnik, Adam Walocha, Wojciech Ogonowski, Wiktor Forjasz et autres

Abstract We present YOSO (you only shot once), a single-frame phase retrieval framework for digital in-line holographic microscopy (DIHM) in which supervised deep learning is used to numerically generate an additional hologram corresponding to different defocus distance, creating a so-called multi-height dataset, …

Incoherent shearing interferometry with optimization-based phase recovery for robust quantitative phase imaging

Piotr Zdańkowski, Julianna Winnik, Maciej Trusiak, Damian Suski

Quantitative phase imaging (QPI) benefits from compact, stable interferometric architectures that remain robust outside vibration-isolated laboratories. Here, we present an incoherent, common-path shearing interferometry approach paired with an optimization-based phase recovery that improves quantitative accuracy while simplifying system calibration. The system is …
