Quantitative EUV ptychography reveals nanoscale morphological responses of bacteria under physiological and antibiotic stress
Chang Liu, Leona Licht, Christina Wichmann +7
Table-top extreme ultraviolet (EUV) ptychography enables nanoscale, label-free, and quantitative imaging with intrinsic elemental sensitivity, offering a unique modality for subcel…
Bayesian multi-exposure image fusion for robust high dynamic range ptychography
Shantanu Kodgirwar, Lars Loetgering, Chang Liu +6
The limited dynamic range of the detector can impede coherent diffractive imaging (CDI) schemes from achieving diffraction-limited resolution. To overcome this limitation, a straig…
Broadband ptychography using curved wavefront illumination
Daniel S. Penagos Molina, Lars Loetgering, Wilhelm Eschen +2
We examine the interplay between spectral bandwidth and illumination curvature in ptychography. By tailoring the divergence of the illumination, broader spectral bandwidths can be…
High-speed and wide-field nanoscale table-top ptychographic EUV imaging and beam characterization with a sCMOS detector
Wilhelm Eschen, Chang Liu, Daniel S. Penagos Molina +3
We present high-speed and wide-field EUV ptychography at 13.5 nm wavelength using a table-top high-order harmonic source. By employing a scientific complementary metal oxide semico…
PtyLab.m/py/jl: a cross-platform, open-source inverse modeling toolbox for conventional and Fourier ptychography
Lars Loetgering, Mengqi Du, Dirk Boonzajer Flaes +11
Conventional (CP) and Fourier (FP) ptychography have emerged as versatile quantitative phase imaging techniques. While the main application cases for each technique are different,…
Visualizing the ultra-structure of microorganisms using table-top extreme ultraviolet imaging
Chang Liu, Wilhelm Eschen, Lars Loetgering +10
Table-top extreme ultraviolet (EUV) microscopy offers unique opportunities for label-free investigation of biological samples. Here, we demonstrate ptychographic EUV imaging of two…
Material-specific high-resolution table-top extreme ultraviolet microscopy
Wilhelm Eschen, Lars Loetgering, Vittoria Schuster +9
Microscopy with extreme ultraviolet (EUV) radiation holds promise for high-resolution imaging with excellent material contrast, due to the short wavelength and numerous element-spe…
Real-time phase-retrieval and wavefront sensing enabled by an artificial neural network
Jonathon White, Sici Wang, Wilhelm Eschen +1
In this manuscript we demonstrate a method to reconstruct the wavefront of focused beams from a measured diffraction pattern behind a diffracting mask in real-time. The phase probl…
Broadband holography-assisted coherent imaging -- towards attosecond imaging at the nanoscale
Wilhelm Eschen, Sici Wang, Chang Liu +7
In recent years nanoscale coherent imaging has emerged as an indispensable imaging modality allowing to surpass the resolution limit given by classical imaging optics. At the same…
Wavelength-scale ptychographic coherent diffractive imaging using a high-order harmonic source
Getnet K. Tadesse, Wilhelm Eschen, Robert Klas +9
Ptychography enables coherent diffractive imaging (CDI) of extended samples by raster scanning across the illuminating XUV/X-ray beam thereby generalizing the unique advantages of…
