Digital shearography is proposed to study the out-plane deformation of the Portevin-Le Chatelier (PLC) band during tensile tests in an Al alloy. The geometrical shape and propagation of the PLC bands are visualized in real time through fringe pattern in subtracted images. In 1/15 s, the maximum out-plane displacement is 245 nm within the PLC band. The displacement distribution is asymmetric while in fringe pattern, the white fringe is narrower in the front of the PLC band than in the rear. In addition, the evolution processes of position shifting and inclination transition of the PLC bands are presented in detail.
