Internal residual stress measurement on plates, train wheels, and thick structures using proprietary sensors and scanners. The technique uses two orthogonal linearly polarized Shear Horizontal waves at 0 and 90 degrees to provide a birefringence measurement which is directly correlated with internal stress.
