Abstract

L’invention concerne un système de mesure acoustique picoseconde (100) pour l’analyse d’un échantillon (5). Selon l’invention, le système comprend un moyen de transduction ayant une première interface (6) en contact avec un substrat transparent (4) et une seconde interface (3) en contact avec l’échantillon (5), une première source laser (101) configurée pour générer un faisceau pompe (201), une seconde source laser (102) configurée pour générer un premier faisceau sonde (203) et un second faisceau sonde (204), ledit faisceau pompe étant configuré pour générer des ondes acoustiques dans le moyen transducteur (4), ledit premier faisceau sonde étant configuré de manière à détecter en temps réel une variation du coefficient de réflexion acoustique de la seconde interface (3) par couplage élasto-optique, ledit second faisceau sonde (204) étant configuré de manière à détecter en temps réel les oscillations de Brillouin liées à l’interaction Brillouin entre ledit second faisceau sonde (204) et une portion des ondes acoustiques se propageant dans l’échantillon, un système de photodétection (116, 117) configuré pour mesurer simultanément et au même point de l’échantillon un signal de variation de la réflectivité au niveau de la seconde interface (3) liée aux oscillations de Brillouin et un signal de variation de la réflectivité au niveau de la première interface (6) liée à une variation du coefficient de la réflexion acoustique.
