Laser-induced acoustic detection of shallow-buried objects

Abstract:

A Laser-induced acoustic technique has been demonstrated for the potential application of underground object detection. The high acoustic impedance mismatch between granular soil and buried mine (usually landmines are made from plastic, rubber and metal) gives good contrast for detection. We obtained 3-D images of underground objects by scanning a pulsed laser across the surface of the ground and keeping the acoustic detector at relatively fixed position with respect to the laser spots. A sig...
