Ultrasound Image

A two-in-one technology provides 3D images of structural defects in metallic structures that can develop in aircraft. The system, developed by Tohoku University researchers in Japan in collaboration with Los Alamos National Laboratory in the US, combines the strengths of two different devices to produce high-resolution 3D images of defects.

The system incorporates a piezoelectric transducer and a laser Doppler vibrometer. Although tested only on defects in metallic materials, the technology can be applied to other materials as well.
