The mapping relationship between the mode shapes of a plastic landmine’s upper casing and its laser speckle interference signal was studied. The mode shape function of a landmine’s upper casing is established according to the vibration equation of its thin circular plate. Then, based on the principle of laser shearing speckle interference and the time-average method of a CCD camera, we mapped the out-of-plane displacement of the mode shape to the phase of the interference laser. The study shows that the different mode shapes of the landmine correspond to the unique Bessel fringes. Furthermore, the Bessel fringes of two modes are simulated, and the corresponding experiments were carried out. Both the numerical and experimental results confirm the theoretical conclusions, the research in this paper can provide theoretical evidence for realizing the rapid scanning technology of acoustic-optics landmine detection.
