Hybrid spectral-spatial domain registration for nanometric tracking in digital in-line holographic microscopy
Kamil Kalinowski, Mikolaj Rogalski, Piotr Arcab +3
Digital in-line holographic microscopy enables label-free tracking and metrology, but achieving nanometric sub-pixel displacement accuracy over a wide capture range remains challen…
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…
High Space-bandwidth Product Label-free Examination of iPSC-derived Brain Organoids via Fourier Ptychographic Microscopy
Mikolaj Krysa, Mikolaj Rogalski, Piotr Arcab +7
Fourier ptychographic microscopy (FPM) is a promising quantitative phase imaging technique that enables high-resolution, label-free imaging over a large field-of-view. Here, we pre…
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…
Doubling the field of view and eliminating the replica overlap problem in common-path shearing quantitative phase imaging
MikoÅaj Rogalski, Piotr ZdaÅkowski, Matyas Heto +6
Quantitative phase imaging (QPI) enables label-free, high-contrast visualization of transparent specimens, but its common implementation in off-axis digital holographic microscopy…
