Figure

Figure 1: Schematic of the configuration: The initial condition is located around z 0 , the measurement region is located around x 0 (the dotted square for the computation of v or the dotted line for the computation of w), the displacement is reconstructed
Figure 2: Schematic of the two configurations presented, where (x 0 , z 0 ) respectively are the source and observation positions and y 0 the position where the displacement τ is recovered.
Figure 3 represents the reconstruction of τ (y 0 ) · φ for different random realization of V y 0 which is numerically given by the formula
Figure 4: Reconstructed displacement in both directions compared to the exact oscillating displace- displace-ment given by (20).
