3D-SAFT Ultrasonic Inspection Equipment “MatrixeyeTM”

3D ultrasonic inspection equipment “Matrixeye” can visualize defects as 3D image with good resolution by the 3D SAFT (Synthetic Aperture Focusing Technique) imaging method. High-speed 3D SAFT imaging process can be achieved by the developed parallel signal process of the ultrasonic echo data collected by a linear or a matrix-array ultrasonic probe. It has the following features. •3D image with high resolution can be visualized by the small number of elements. •Resolution of 3D image is almost constant against a change of depth and a probe frequency. •Sensitivity of 3D image is good because S/N ratio is improved by SAFT process itself. In this report, we introduce development of 3D-SAFT technology, its application and the current development activity.
