Multistatic anisotropic travel-time as a tensor tomography problem
Naeem Desai, Oliver Graham, Sean Holman +1
Travel-time imaging problems seek to reconstruct an image of reflectivity of a scene by measuring travel time (and amplitude, phase) of electromagnetic or acoustic signals, such as…
On Regularisation of Coherent Imagery with Proximal Methods
F. M. Watson, W. R. B. Lionheart, J. Hellier
In complex-valued coherent inverse problems such as synthetic aperture radar (SAR), one may often have prior information only on the magnitude image which shows the features of int…
Resolving Full-Wave Through-Wall Transmission Effects in Multi-Static Synthetic Aperture Radar
Francis Watson, Daniel Andre, William Robert Breckon Lionheart
Through-wall synthetic aperture radar (SAR) imaging is of significant interest for security purposes, in particular when using multi-static SAR systems consisting of multiple distr…
Direct inversion of the Longitudinal Ray Transform for 2D residual elastic strain fields
C. M. Wensrich, S. Holman, M. Courdurier +3
We examine the problem of Bragg-edge elastic strain tomography from energy resolved neutron transmission imaging. A new approach is developed for two-dimensional plane-stress and p…
Properties of Generalised Magnetic Polarizability Tensors
P. D. Ledger, W. R. B. Lionheart
We present new alternative complete asymptotic expansions for the time harmonic low--frequency magnetic field perturbation caused by the presence of a conducting permeable object a…
Recovering the second moment of the strain distribution from neutron Bragg edge data
Kyle Fogarty, Evelina Ametova, Genoveva Burca +4
Point by point strain scanning is often used to map the residual stress (strain) in engineering materials and components. However, the gauge volume and hence spatial resolution is…
