Abstract

L'invention est relative à la modulation d'un faisceau lumineux. Le dispositif comprend un générateur d'onde acoustique et une substance acoustico-optique qui contient un composé polyphénylé, stériquement encombré, présentant un coefficient d'atténuation du son, mesuré à 25 degrés C, inférieur à environ 10 dB/cm pour une fréquence de 40 MHz. Application à la réalisation de dispositifs acoustico-optiques comprenant un transducteur acoustique associé à la substance acoustico-optique.
