5.1 Seismic wave visualization
As part of studies into methods for detecting objects buried in the ground, such as mines, ISL has been experimenting with the optical seismic detection technique . In fact, the presence of a buried object can change the local characteristics of the ground, creating an inhomogeneity that could alter the propagation of a seismic wave. Assuming that this modification is sufficient at the surface (a few µm), visualization by holographic interferometry would reveal the...
