2017-05-19 Twin crystal shear wave transducers hold two crystals mounted at inward angles that provide improved near-surface resolution and superior signal-to-noise ratio. Ideal for inspecting thin materials for small flaws, occurring directly under the surface. Refracted Shear Waves. If the angle of the wedge is sufficient (around 38° for example) it is possible to produce shear waves into the part.
