Abstract
The optical flow based approach to measure displacements at impact response was recently shown to give very good results where the subpixel resolution is at the level of 1/10000 of a pixel. This study researches the applicability of the optical flow approach to the damping identification with the Morlet Wave methods. The Morlet wave method bases on the continuous wavelet transform but is not impacted by the edge-effect. It was shown that the damping identification is reliable and opens up new questions with regards to the spatial distribution of the identified damping.
