The example shows an application of NDT on a 30m CFK yacht mast (lower left). The time average result of the SE1 measurement and dynamic loading by our piezo-shaker (lower right) is indicating a larger delimitation below the surface starting from a small visible crack. Usually small cracks are often seen on the surface, but not all are related to delamination, which needs any repair.
