Lateral shearing optical diffraction tomography of brain organoid with reduced spatial coherence
Pawel Goclowski, Julianna Winnik, Vishesh Dubey +6
Optical diffraction tomography (ODT) is a powerful technique for quantitative, label-free reconstruction of the three-dimensional refractive index (RI) distribution of biological s…
YOSO: single-frame Gerchberg-Saxton phase retrieval with AI-based data augmentation for in-line holography
Julianna Winnik, Adam Walocha, Wojciech Ogonowski +9
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 numeri…
Near-infrared lensless holographic microscopy on a visible sensor enables label-free high-throughput imaging in strong scattering
Emilia Wdowiak, Piotr Arcab, Mikolaj Rogalski +6
Lensless digital holographic microscopy (LDHM) relies on interference between an unscattered reference wave and a weakly scattered object wave - an assumption that rapidly fails in…
Low-dose Chemically Specific Bioimaging via Deep-UV Lensless Holographic Microscopy on a Standard Camera
Piotr Arcab, Mikolaj Rogalski, Karolina Niedziela +11
Deep-ultraviolet (DUV) microscopy can provide label-free biochemical contrast by exploiting the intrinsic absorption of nucleic acids, proteins and lipids, offering chemically spec…
Bayesian inference for precise and uncertainty-quantified single-shot widefield interferometric geometrical nanometrology
Damian Suski, Maria Cywinska, Julianna Winnik +5
Advanced geometrical nanometrology is critical for process control in semiconductor manufacturing, supporting applications in, e.g., photonic integrated circuits, nanoelectronics,…
OSI-flex: Optimization-Based Shearing Interferometry for Joint Phase and Shear Estimation Using a Flexible Open-Source Framework
Julianna Winnik, Damian Suski, Matyáš Heto +4
Shearing interferometry is a common-path quantitative phase imaging technique in which an object beam interferes with a laterally shifted replica of itself, providing high temporal…
