Modelling of Phase Contrast Imaging with X-ray Wavefront Sensor and Partial Coherence Beams [PDF]

open access: yesSensors, 2020
The Hartmann wavefront sensor is able to measure, separately and in absolute, the real δ and imaginary part β of the X-ray refractive index. While combined with tomographic setup, the Hartman sensor opens many interesting opportunities behind the direct ...

Recovery of undamaged electron-density maps in the presence of damage-induced partial coherence in single-particle imaging [PDF]

open access: yesIUCrJ, 2020
Resolving the electronic structure of single biological molecules in their native state was among the primary motivations behind X-ray free-electron lasers. The ultra-short pulses they produce can outrun the atomic motion induced by radiation damage, but

Coherence and Partial Coherence in Interacting Electron Systems [PDF]

open access: yesPhysical Review Letters, 2001
We study coherence of electron transport through interacting quantum dots and discuss the relation of the coherent part to the flux-sensitive conductance for three different types of Aharonov-Bohm interferometers.

Comparison of two novel swept-source optical coherence tomography devices to a partial coherence interferometry-based biometer [PDF]

open access: yesScientific Reports, 2021
To evaluate the repeatability and agreement of corneal and biometry measurements obtained with two swept-source optical coherence tomography (SSOCT) and a partial coherence interferometry-based device. This is a cross-sectional study. Forty-eight eyes of

Comparison between spectral-domain optical coherence tomography-based and partial coherence interferometry-based biometry [PDF]

open access: yesScientific Reports
We compared axial length (AL) measurements using spectral-domain optical coherence tomography (SD-OCT)-based and partial coherence interferometry (PCI)-based biometry in eyes with various chorioretinal diseases.

Comparison of Eye Axial Length Measurements Taken Using Partial Coherence Interferometry and OCT Biometry [PDF]

open access: yesVision
This study evaluates the inter-device measurement properties of partial coherence interferometry (PCI) and spectral domain optical coherence tomography (SD-OCT) in measuring axial length, particularly for myopia management.

Comparison of two swept-source optical coherence tomography biometers and a partial coherence interferometer. [PDF]

open access: yesPLoS ONE, 2019
PurposeTo compare biometry and prediction of postoperative refractive outcomes obtained by two swept-source optical coherence tomography (SS-OCT) biometers (IOLMaster 700 and Argos), and a partial coherence interferometry (IOLMaster ver 5.4 ...

Agreement between a new fully automatic ocular biometer based on optical low-coherence reflectometry and an optical biometer based on Scheimpflug imaging combined with partial coherence interferometry [PDF]

open access: yesBMC Ophthalmology
Background To analyze the difference and agreement between measurements obtained by a new fully automatic optical biometer, the SW-9000 μm Plus, based on optical low-coherence reflectometry (OLCR) and a commonly used optical biometer (Pentacam AXL) based
