High-fidelity state detection and tomography of a single ion Zeeman qubit [PDF]

open access: yes, 2011
We demonstrate high-fidelity Zeeman qubit state detection in a single trapped 88 Sr+ ion. Qubit readout is performed by shelving one of the qubit states to a metastable level using a narrow linewidth diode laser at 674 nm followed by state-selective ...

Electron tomography

open access: yesMaterials Today, 2004
Electron tomography is a mature 3D nanocharacterisation technique with applications to almost all classes of materials. It offers 3D resolution at the nanometre level, or better, in volumes of a few hundred nanometres—precisely the playground of the nanoscientist.

All fiber polarization insensitive detection for spectrometer based optical coherence tomography using optical switch

open access: yes, 2019
Polarization dependent image artifacts are common in optical coherence tomography imaging. Polarization insensitive detection scheme for swept source based optical coherence tomography systems is well established but is yet to be demonstrated for all ...

Computed tomography-osteoaboorptiometry [PDF]

open access: yes, 1990
A method of making a visual display of subchondral mineralization in the major synovial joints is described. Unlike existing procedures, it can be used on the living subject. A modified application of computed tomography-densitometry, computed tomography-

Quantum Tomography twenty years later

open access: yes, 2015
A sample of some relevant developments that have taken place during the last twenty years in classical and quantum tomography are displayed. We will present a general conceptual framework that provides a simple unifying mathematical picture for all of ...

Fourier domain preconditioned conjugate gradient algorithm for atmospheric tomography [PDF]

open access: yes, 2006
By 'atmospheric tomography' we mean the estimation of a layered atmospheric turbulence profile from measurements of the pupil-plane phase (or phase gradients) corresponding to several different guide star directions.

Radiomics nomogram for preoperative differentiation of pulmonary mucinous adenocarcinoma from tuberculoma in solitary pulmonary solid nodules

open access: yesBMC Cancer, 2023
Objective To develop and validate predictive models using clinical parameters, radiomic features and a combination of both for preoperative differentiation of pulmonary nodular mucinous adenocarcinoma (PNMA) from pulmonary tuberculoma (PTB).

The Power of Low Frequencies: Faraday Tomography in the sub-GHz regime

open access: yes, 2018
Faraday tomography, the study of the distribution of extended polarized emission by strength of Faraday rotation, is a powerful tool for studying magnetic fields in the interstellar medium of our Galaxy and nearby galaxies.

Stripe sensor tomography [PDF]

open access: yes, 2008
We introduce a general concept of tomographic imaging for the case of an imaging sensor that has a stripelike shape. We first show that there is no difference, in principle, between two-dimensional tomography using conventional electromagnetic or ...

Jet tomography

open access: yes, 2004
I summarize the recent advances in jet tomographic studies of cold and hot nuclear matter based on perturbative QCD calculations of medium-induced gluon bremsstrahlung.
