Abstract

Die Erfindung betrifft eine Anordnung und ein Verfahren zur Ortung von magnetischen oder magnetisierbaren Objekten, die sich in nichtmagnetischen Medien befinden. Zur Erhöhung der Nachweistiefe für derartige Objekte sowie zur eindeutigen Erfassung ihrer Form, Lage und Strukturen in einzelnen Nachweisebenen ist mindestens ein Sensor in einem primären Magnetfeld eines Magnetfelderzeugers angeordnet, wobei die Magnetisierungsverteilung des Magnetfeldes in der Nähe des jeweiligen Sensors homogen oder hinsichtlich ihres örtlichen Verlaufs bekannt ist.
