3D micro-scale deformations of wood in bending: Synchrotron radiation μCT data analyzed with digital volume correlation
TL;DR: The applied combination of synchrotron radiation micro-computed tomography and digital volume correlation for the deformation analysis of wood under bending stress is a novel application in wood material science and offers the potential for the simultaneous observation of structural changes and quantified deformations during in situ micro-mechanical experiments.

Calibration and evaluation of optical systems for full-field strain measurement
Eann A. Patterson,Erwin Hack,Philippe Brailly,Richard L. Burguete,Qasim Saleem,Thorsten Siebert,Rachel A. Tomlinson,Maurice Whelan +7 more
TL;DR: A classification system for the steps in the measurement process is proposed and allows the development of a unified approach to diagnostic testing of components or sub-systems in an optical system for strain measurement based on any optical technique.
