Abstract

Système ne nécessitant pas de longs registres à décalage. Il comprend des moyens pour produire et diriger une salve d'ultrasons dans une zone d'analyse, un réseau de transducteurs il qui sont le siège de signaux d'écho, le temps d'apparition d'un signal d'écho dans un transducteur considéré dépendant de la distance entre ce transducteur et le point d'objet générateur d'écho, des moyens 28, 32 pour former un certain nombre de premiers signaux de démodulation ayant sensiblement la même valeur de déphasage entre, d'une part, les premiers signaux de démodulation et, d'autre part, les signaux d'écho auxquels ces signaux de démodulation sont respectivement affectés, des moyens 25, 31 pour démoduler les signaux d'écho formés dans les transducteurs pour former un premier signal démodulé, des moyens 27, 33 pour retarder chaque premier signal démodulé, de façon que tous les signaux démodulés et retardés apparaissent simultanément, des moyens 35 pour faire la somme des premiers signaux démodulés et retardes et obtenir ainsi un premier signal de sommation. Application au diagnostic médical.
