Lock-in vibration retrieval based on high-speed full-field coherent imaging

E Meteyer, S Montresor, F Foucart, J Le Meur… - Scientific Reports, 2021 - nature.com
The use of high-speed cameras permits to visualize, analyze or study physical phenomena
at both their time and spatial scales. Mixing high-speed imaging with coherent imaging
allows recording and retrieving the optical path difference and this opens the way for
investigating a broad variety of scientific challenges in biology, medicine, material science,
physics and mechanics. At high frame rate, simultaneously obtaining suitable performance
and level of accuracy is not straightforward. In the field of mechanics, this prevents high …
