Abstract

DISPOSITIF POUR MESURER LES PROPRIETES ACOUSTIQUES ET LES VARIATIONS DE CES PROPRIETES DANS UN ECHANTILLON DE LIQUIDE, DE GAZ, DE PLASMA OU DE SOLIDE. ON APPLIQUE LES SIGNAUX D'UNE SOURCE DE FREQUENCE VARIABLE A L'ECHANTILLON AU MOYEN D'UN TRANSDUCTEUR AFIN DE PRODUIRE DES ONDES ACOUSTIQUES DANS CELUI-CI. ON INTERROMPT PERIODIQUEMENT L'APPLICATION DE CES SIGNAUX PENDANT QUELQUES INSTANTS. DES MOYENS SONTCONNECTES AU TRANSDUCTEUR POUR RECEVOIR LES SIGNAUX ACOUSTIQUES RESULTANT PENDANT LES INTERRUPTIONS AFIN DE PRODUIRE UN SIGNAL DE COMMANDE REPRESENTATIF DE LA DIFFERENCE ENTRE LES FREQUENCES DE LA SOURCE DE FREQUENCE VARIABLE ET DE LA POINTE DE RESONANCE MECANIQUE DE L'ECHANTILLON. CE SIGNAL DE COMMANDE EST APPLIQUE A LA SOURCE DE FREQUENCE VARIABLE POUR MAINTENIR SES SIGNAUX DE SORTIE A LA FREQUENCE DE LA POINTE DE RESONANCE MECANIQUE DE L'ECHANTILLON. LES CHANGEMENTS DE FREQUENCE DE LA SOURCE VARIABLE SONT REPRESENTATIFS DU DECALAGE DE LA FREQUENCE DE LA POINTE DE RESONANCE MECANIQUE ET L'AMPLITUDE DES SIGNAUX ACOUSTIQUES INDIQUE L'ATTENUATION DES SIGNAUX DANS L'ECHANTILLON.
