The aim of this work is to provide 3D dynamic displacement measurement of harmonic loading for comparison with Magnetic Resonance Imaging (MRI) methods. A soft cubic gelatin sample is monitored and loaded by a fast-acquisition setup that includes a piezo actuator and a translatable laser beam. Displacement fields are measured by Digital Volume Correlation and the viscoelastic properties fields are identified using a Finite Element Model Updating (FEMU) method.
