Abstract

Buried mine detection is a very complex problem. Many types of mines contain few metallic parts, which complicates the detection with classical electromagnetic systems. In this work we have studied the application of holographic interferometry techniques to the visualization of seismic wave propagation. Perturbations of the wave propagation can reveal the presence of a buried object. At first, classical holographic interferometry is tested to follow the propagation of the seismic wave. To make the holographic acquisition system more portable, we have also tested the speckle interferometry technique. Results concerning both methods are shown and discussed.
