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…
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…
