Les techniques de détection optique d'impulsions photoacoustiques ouvrent de nouveaux horizons aux mesures ultrasonores et/ou spectroscopiques dans des environnements hostiles (tels que flammes, fluides corrosifs, aérosols dangereux, etc.) et, de plus, permettent une compréhension fondamentale des processus de génération d'impulsions photoacoustiques. Cette publication fournit des exemples de telles applications dans le nouveau domaine de 'détection optique d'ultrasons' (où les mesures des paramètres ultrasonores caractérisant le flux, la température, etc. sont faites optiquement), ainsi qu'en 'spectroscopie optique d'ultrasons' (où la dispersion et les relaxations ultrasonores sont mesurées optiquement).Noncontact techniques of optical pro...
