Demonstration of pressure wave observation by acousto-optic sensing using a self-mixing interferometer

HIGHLIGHTS

• who: Su00e9bastien Maqueda and colleagues from the Laboratoire d`Analyse et d`Architecture des Systu00e8mes (LAAS-CNRS), Centre National de la Recherche , Rue Charles Camichel, Toulouse, France have published the research work: Demonstration of Pressure Wave Observation by Acousto-Optic Sensing Using a Self-Mixing Interferometer, in the Journal: Sensors 2023, 23, 3720. of /2023/
• what: The authors demonstrate that a compact and inexpensive interferometric sensor based on the self-mixing effect in the laser cavity can be used for the characterization of shock waves. In this paper, another optical approach is proposed.
