(PresseBox) (München, )
In der Bauteileprüfung ist Ultraschall eine bewährte Technologie - doch die Auswertung ist bislang ziemlich aufwändig. Fraunhofer-Forscher stellen vom 7. bis 11. April auf der Hannover Messe ein optimiertes Verfahren vor: Es erlaubt eine schnelle und zuverlässige Materialprüfung anhand von 3D-Aufnahmen (Halle 2, Stand D18).
