AB - <p style="text-align: justify;">The purpose of this paper is to numerically realize the inverse scattering
scheme proposed in [19] of reconstructing complex elastic objects by a single far-field
measurement. The unknown elastic scatterers might consist of both rigid bodies and
traction-free cavities with components of multiscale sizes presented simultaneously.
We conduct extensive numerical experiments to show the effectiveness and efficiency
of the imaging scheme proposed in [19]. Moreover, we develop a two-stage technique,
which can significantly speed up the reconstruction to yield a fast imaging scheme.</p>
