Paper Abstract
The preliminary numerical simulation results obtained in the analysis of a landmine detection system based on laser
excitation of acoustic - seismic waves in the soil and observing its surface vibration above the embedded landmine are
presented. The presented numerical simulations comprise three main parts: 1) Laser oscillator and laser beam
propagation and absorption in soil; a laser oscillator operated in Q-switched regime is considered; different laser
wavelengths are investigated. 2) Acoustic - seismic wave generation by absorption in soil of laser pulse energy; 3)
Evaluation of acoustic - seismic wave generation by the buried in soil landmine; 4) Comparison of Distributed Feed-
Back Fiber Laser (DFB-FL) and Laser Doppler Vibrometer (LDV) detector used for soil vibrations evaluation. The
above mentioned numerical simulation is dedicated for evaluation of an integrated portable detection system.
