High-Sensitivity X-ray Phase Imaging System Based on a Hartmann Wavefront Sensor
Condensed Matter, 2021 The Hartman wavefront sensor can be used for X-ray phase imaging with high angular resolution. The Hartmann sensor is able to retrieve both the phase and absorption from a single acquisition.

Digital Fourier Transform Holography Using a Beam Displacer
Engineering Proceedings, 2023 Fourier transform holography overcomes the phase recovery challenge through recording complex field information of the object in an interference pattern recorded at the far field, i.e., Fourier plane.

Intelligent phase imaging guided by physics models
物联网学报, 2023 Implicit neural representation characterizes the mapping between the signal’s coordinate to its attributes, and has been widely used in the optimization of inverse problems by embedding the physics process into the loss function.However, the implicit ...

Phase Imaging through Scattering Media Using Incoherent Light Source
Photonics, 2023 Phase imaging normally employs coherent a light source while an incoherent light source is not preferred due to its random wavefront. Another challenge for practical phase imaging is imaging through scattering media, which scatter the photons in a random

Optics Express, 2017 Lensless quantitative phase imaging is of high interest for obtaining a large field of view (FOV), typically the size of the camera chip, to observe biological cell material with high contrast. It has the potential to be widely spread due to its inherent simplicity. However, the tradeoff is the added complexity due to the illumination.

Iterative Restoration of the Fringe Phase (REFRASE) for QSM
Frontiers in Neuroscience, 2021 In quantitative susceptibility mapping (QSM), reconstructed results can be critically biased by misinterpreted or missing phase data near the edges of the brain support originating from the non-local relationship between field and susceptibility.

Neutron Phase Imaging and Tomography
Physical Review Letters, 2006 We report how a setup consisting of three gratings yields quantitative two- and three-dimensional images depicting the quantum-mechanical phase shifts of neutron de Broglie wave packets induced by the influence of macroscopic objects. Since our approach requires only a little spatial and chromatic coherence it provides a more than 2 orders of magnitude
