Part of the Acoustical Imaging book series (ACIM, volume 29)


We have developed a high-frequency acoustical imaging system to detect porosity and single pores in the surface-near range (0.5–2 mm depth) in die-casting components. The scanning system employing a robot allows one to inspect components with curved surfaces.
