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 …

We show the ability to determine the relative phase between the object and a reference
scatterer by tuning the overall intensity and phase of the reference wave. The proposed …

We present a phase reconstruction scheme for X-ray near-field holographic imaging based
on a separability constraint for probe and object. In order to achieve this, we have devised …

We have implemented a deterministic method for solving the phase problem in hard x-ray in-
line holography which overcomes the twin image problem. The phase distribution in the …

X-ray phase contrast imaging based on free space propagation relies on phase retrieval to
obtain sharp images of micro-and nanoscale objects, with widespread applications in …

Phase measurement is a long-standing challenge in a wide range of applications, from X-
ray imaging to astrophysics and spectroscopy. While in some scenarios the phase is …

Fourier transform holography (FTH) is a noise-resistant imaging technique which allows for
nanometer spatial resolution x-ray imaging, where the inclusion of a small reference …

Inline holography is a common phase-contrast imaging method which uses free-space
propagation to encode the phase signal into measured intensities. However, quantitative …

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 …

Lensless imaging is a high potential and currently intensely targeted research goal, in view
of those fields of applications for which aberration-free high-resolution lenses are not …
