... to be ultrasonically resolvable and instead gives rise to speckle in the same way as tissue in medical imaging. However, in NDE for flaw detection (rather than materials characterization), the material scattering is undesired coherent noise. It is coherent noise from both material microstructure and other sources (e.g...
