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…
The mixture of glycerin with tartrazine: a solution to reversibly increase tissue transparency for in vitro quantitative phase imaging
Mikolaj Krysa, Anna Chwastowicz, Malgorzata Lenarcik +3
Thick tissue sections strongly scatter and absorb light, which limits transmission-based label-free examination via quantitative phase imaging (QPI) modalities. Here we introduce a…
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…
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…
