A single beam laser Doppler vibrometer (LDV) has been used in acoustic-to-seismic landmine detection in a stop-andstare scanning mode [Sabatier, J. M. and Xiang, N. IEEE Trans. Geoscience and Remote Sensing 39, 2001, pp.11461154.; Xiang, N. and Sabatier, J. M., J. Acoust. Soc. Am. 113, Mar. 2003]. One of the major requirements is the operational scanning speed in the acoustic detection methods....
