Industrial system for composites inspection using SAUL

The SAUL technique enables the transmission of an incident wave-front parallel to any complex surface. One specimen presenting 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 (e.g., CFRP stringers, stiffeners).
