Ultrasound is a proven technology in components testing, but until now eva- luating the data has always been quite a time-consuming process. At the Hannover Messe from April 7-11, Fraunhofer researchers will be presenting their optimized ultrasonic testing solution – a method for testing materials quickly and reliably with the help of 3D images (Hall 2, Booth D18). Bats always know where they are, even in complete darkness. It’s not that they have amazing vision: rather, these nocturnal creatures “scan” their surroundings by continually emitting sounds inaudible to humans. Whenever these ultrasonic waves hit an obstacle, they are sent back as an echo. The longer an echo takes to return, the further away the object is. We humans also utilize this echolocation principle; in industry, for example, where ultrasound provides an effective way to test components. Ultrasonic waves emitted from a probe are used to detect the tiniest tears or material flaws that are not externally visible. Until now this process involved an employee guiding the probe along the component by hand, with the reflected signals appearing as curves on the probe’s display. Simple cross-sectional images of the area being examined can also be generated, providing experienced examiners with enough
