Abstract
The present invention relates to a method of performing subsurface imaging of embedded structures in a substrate underneath a substrate surface, the method comprising the steps of applying, using a signal application actuator, an acoustic input signal to the substrate, detecting, using a vibration sensor, a return signal from the substrate and analyzing the return signal for obtaining information on the embedded structures, for enabling imaging thereof wherein the step of applying the acoustic input signal comprises applying a discontinuous signal of an acoustic signal component to the substrate, the acoustic signal component having a frequency above 1 gigahertz, such that the return signal includes a scattered fraction of the discontinuous signal scattered from the embedded structures. The invention further relates to a system.
