A hydrophone array includes hydrophones having an electret means and may have TFT FETs to generate current in response to received longitudinal wave signals. The arrangement may also be used to transmit longitudinal wave signals. Storage capacitors may be coupled to each TFT FET output to act as sample and hold means. Digital switches may allow the sample and hold circuit to both reset and measure the output of the hydrophone element. Data lines may be used to indicate the location of the received signal on the longitudinal wave detector sensor array.

La présente invention concerne un réseau hydrophone qui comprend des hydrophones ayant un moyen d'électret et peut avoir des FET TFT pour générer un courant en réponse aux signaux d'onde longitudinale reçus. L'agencement peut aussi être employé pour transmettre des signaux d'onde longitudinale. Les condensateurs de stockage peuvent être couplés à chaque sortie FET TFT pour agir comme échantillon et moyen de retenue. Les commutateurs numériques peuvent permettre à l'échantillon et au circuit de retenue de réinitialiser et mesurer la sortie de l'élément hydrophone. Les lignes de données peuvent servir à indiquer l'emplacement du signal reçu sur le réseau du capteur de détecteur d'ondes longitudinales.
