Industrial system for composites inspection using SAUL

The Surface Adapting Ultrasound, or SAUL, technique enables the transmission of an incident wave-front parallel to any complex surface. One specimen featuring variable geometries —flat, concave or convex surfaces— can be entirely controlled using a unique probe such as a matrix array with a flat active aperture. The real-time adaptive processing is illustrated through measurements obtained with typical aircraft composite structures such as CFRP stringers and stiffeners.
