The rise of microplastic (MP) pollution in the environment has been bolstering concerns
regarding MPs' unknown environmental fate, transport, and potential toxicity toward living …

Inverse problems with Poisson data arise in many photonic imaging modalities in medicine,
engineering and astronomy. The design of regularization methods and estimators for such …

Propagation-based phase-contrast X-ray imaging is by now a well established imaging
technique, which–as a full-field technique–is particularly useful for tomography applications …

We describe and demonstrate an optimization-based X-ray image reconstruction framework
called Adorym. Our framework provides a generic forward model, allowing one code …

In electron microscopy, detailed insights into nanoscale optical properties of materials are
gained by spontaneous inelastic scattering leading to electron-energy loss and …

Based on phase retrieval, lensless coherent imaging and in particular holography offers
quantitative phase and amplitude images. This is of particular importance for spectral ranges …

Non-interferometric quantitative phase imaging based on Transport of Intensity Equation
(TIE) has been widely used in bio-medical imaging. However, analytic TIE phase retrieval is …

The directional polarimetric camera (DPC) is a remote-sensing instrument for the
characterization of atmospheric aerosols and clouds by simultaneously conducting spectral …

The following article describes a method for 3D reconstruction of multi-material objects
based on propagation-based X-ray phase-contrast tomography (PB-CT) with phase retrieval …

X-ray propagation-based imaging techniques are well established at synchrotron radiation
and laboratory sources. However, most reconstruction algorithms for such image modalities …
