Description
This doctoral lecture details the technical principles of neutron and X-ray tomography, beginning with the physical definitions of digital imaging and the mechanisms of beam collimation and neutron detection, 3D volume reconstruction from 2D projections and the application of image analysis protocols for structural quantification. Particular focus is placed on Digital Volume Correlation (DVC) as a method for measuring internal displacement and strain fields. These methodologies are demonstrated through a series of case studies involving fluid transport in porous media and the characterisation of energy materials, including battery and fuel cell architectures.
