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…

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…

Gigavoxel-Scale Multiple-Scattering-Aware Lensless Holotomography

Mikolaj Rogalski, Julianna Winnik, Julia Dudek +6

Holotomography (HT) has revolutionized quantitative label-free 3D imaging, yet conventional lens-based implementations are fundamentally constrained in field-of-view (FOV) and imag…
