Abstrakt: This work presents X-ray computed tomography of a harmonically oscillating elastic beam. The tomographic imaging is achieved by obtaining projections of the object in its maximum amplitude to capture the eigenmode of the beam using a triggered computed tomography method synchronized with the oscillation of the beam. Related instrumentation, experimental methodology and data post-processing are presented. Results are demonstrated on the reconstructed 3D images of the polymeric oscillating beam in its deformed shape corresponding with the harmonic excitation using the first eigenfrequency. A comparison with conventional non-synchronized tomography of the oscillating beam in its first eigenfrequency is presented to highlight fundamental advantages on such tomographical imaging.
