Phase Corrections With Adaptive Optics and Gerchberg-Saxton Iteration: A Comparison

open access: yesIEEE Access, 2019
Free space optical communications technique is the promising alternative for the access/fronthual networks to relieve the traffic congestion. The turbulence in the free space channel, however, could cause the phase distortions in optical signals, thus ...

Phase Error Correction in Time-Averaged 3D Phase Contrast Magnetic Resonance Imaging of the Cerebral Vasculature. [PDF]

open access: yesPLoS ONE, 2016
PURPOSE:Volume flow rate (VFR) measurements based on phase contrast (PC)-magnetic resonance (MR) imaging datasets have spatially varying bias due to eddy current induced phase errors.

Application of phase correction to improve the characterization of photooxidation products of lignin using 7 Tesla Fourier-transform ion cyclotron resonance mass spectrometry

open access: yesFACETS, 2017
Lignin is the second most abundant natural biopolymer and potentially a valuable alternative energy source for conventional fossil fuels. In this study, Fourier-transform ion cyclotron resonance-mass spectrometry (FTICR-MS) in conjunction with phase ...

On phase correction in tomographic research

open access: yesSibirskii zhurnal industrial'noi matematiki, 2020
Under consideration is the problem of improving the contrast of the image obtained by processing tomographic projections with phase distortion. The study is based on the well-known intensity transfer equation. Unlike other works, this equation is solved in a bounded region of variation of the tomographic parameters.

Universal Phase Correction for Quantum State Transfer in One-Dimensional Topological Spin Chains

open access: yesPhotonics
Gap-protected topological channels are a promising way to realize robust and high-fidelity state transfer in quantum networks. Although various topological transfer protocols based on the Su-Schrieffer-Heeger (SSH) model or its variants have been ...

Derivative Expansion and Soliton Masses [PDF]

open access: yes, 1999
We present a simple algorithm to implement the generalized derivative expansion introduced previously by L-H. Chan, and apply it to the calculation of the one-loop mass correction to the classical soliton mass in the 1+1 dimensional Jacobi model. We then

Stepping to phase-perturbed metronome cues: Multisensory advantage in movement synchrony but not correction

open access: yesFrontiers in Human Neuroscience, 2014
Humans can synchronise movements with auditory beats or rhythms without apparent effort. This ability to entrain to the beat is considered automatic, such that any perturbations are corrected for, even if the perturbation was not consciously noted ...
