Pinces acoustiques hautes fréquences pour la manipulation d'objets micrométriques

Jean-Louis Thomas, Michael Baudoin, Roudy Al Sahely

Les pinces acoustiques sont l’équivalent des pinces optiques, elles utilisent un faisceau focalisé pour piéger en trois dimension un objet à l’aide de la pression de radiation. Ces dernières ont permis de faire des manipulation d’objets micro-métrique avec une précision nano-métrique. Néanmoins une…
