Abstract

Procédé pour l'exploration et l'analyse d'une structure volumique par un traitement approprié de signaux représentatifs d'ondes, notamment d'ondes ultrasonores réfléchies ou transmises par cette structure volumique, le traitement consistant à reconstituer ou à analyser la structure volumique à partir des informations lues dans une mémoire de champ, dans laquelle sont calculés pour chaque point de structure, les positions de la mémoire de champ contenant les signaux détectés par les éléments de détection, correspondant aux ondes réfléchies ou transmises par ce point, lesquelles informations dans la mémoire de champ sont lues par une courbe de décodage, le procédé comprenant la détection du signe des signaux détectés, la détection d'une zone utile de ladite courbe de décodage dans laquelle les signaux sont de même signe et le calcul de la position du point analysé à partir d'une intégration des amplitudes des signaux détectés dans la zone utile de la courbe de décodage.
