High-speed holographic metrology: Principle, limitations and application to vibro-acoustics of structures
Résumé
This paper describes the basics of high-speed holographic metrology, its limitations, and its application to the investigation of traveling acoustic waves propagating in mechanical structures. Limits are related to few parameters that must be carefully adjusted for the recording. Applications to vibro-acoustics of structures consider the case of waves propagating after a shock and in an acoustic black hole extremity.
