Paper Abstract

The use of acoustic-to-seismic coupling to detect buried landmines has been successfully demonstrated over the past year. The technique uses a laser Doppler vibrometer (LDV) to measure the velocity of the ground vibration as it is being sonified. As it is currently implemented, the LDV scans individual points on the ground. The technique shows much promise, but it is slow when compared to some other techniques. This work investigates the feasibility of acquiring data with the LDV as the beam moves continuously across the ground. Simple models were developed and experiments were performed to explain the cause of this noises. These result are presented and the feasibility of the approach is discussed. It has been shown that this approach is possible, but that the continuous scanning process introduces noise into the data.
