A system developed by researchers at Tohoku University captures 3D images enabling the detection of defects in metallic structures. The technology, called the piezoelectric and laser ultrasonic system (PLUS), combines the strengths of two different devices to produce its high-resolution 3D images of metallic structure defects, and could enhance safety in power plants and airplanes, among other areas and applications.
In addition to leading to accurate evaluation of material strength, the system could additionally be used to determine how material defects first started to form, said Yoshikazu Ohara, associate professor at Tohoku University.
Currently available “ultrasonic phased arrays” are an effective tool for…READ MORE
