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…
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…
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…
Speckle suppression in digital in-line holographic microscopy through liquid crystal dynamic scattering
Emilia Wdowiak, Nathan Spiller, Tianxin Wang +7
We demonstrate speckle noise reduction in an in-line holographic imaging system using a Zwitterion-doped liquid crystal dynamic scatterer (LCDS) cell diffuser. Integrated into a mi…
Fourier ptychographic microscopy aided with transport of intensity equation for robust full phase spectrum reconstruction
MikoÅaj Rogalski, Juan Martinez-Carranza, Bartosz Górski +8
Fourier ptychographic microscopy (FPM) is a pivotal computational imaging technique that achieves phase and amplitude reconstruction with high resolution and wide field of view, us…
Quantitative phase imaging verification in large field-of-view lensless holographic microscopy via two-photon 3D printing
Emilia Wdowiak, MikoÅaj Rogalski, Piotr Arcab +3
Large field-of-view (FOV) microscopic imaging with high lateral resolution (1-2 microns for high space-bandwidth product) plays a pivotal role in biomedicine and biophotonics, espe…
