Real Time Imaging with Shear Waves and Surface Waves

A chirp focused phased array B-scan imaging system has been employed to obtain cross sectional images in metals. Good quality images with a field of view of 5–20 cm × 5 cm of arrays of holes have been observed using shear waves, Rayleigh waves, Lamb waves, and flexural waves in thin sheets of metal. With 2.5 MHz Rayleigh waves, we have detected and located surface flaws as small as 250 μm deep and 1000 μm diameter.
