Experimental Evidence of Single and Multiple Scattering in Polycrystalline Materials

Ultrasound scatter in heterogeneous 3D microstructures: Parameters affecting multiple scattering

“…Past experimental studies [2,7] have shown that the effects of multiple scattering are dependent upon the focal properties of the transducer used. Notably, these results showed that, when all other inspection parameters are unchanged, multiple scattering effects are more pronounced when a planar transducer is used rather than a focused transducer.…”
