A single beam laser Doppler vibrometer (LDV) has been used in acoustic-to-seismic mode [Sabatier, J.M. and Xiang, N. IEEE Trans. Geoscience and Remote Sensing 39, 2001, pp. 1146-1154; 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. To increase the operational speed, the LDV must move continuously along the ground. An initial effort has demonstrated the feasibility of continuously scanning the ground by controlling the mirrors in a scanning laser vibrometer [Valeau et al., Development of a time-frequency representation for acoustic detection of buried objects, J. Acoust. Soc. Am., 2003 (submitted).]. A continuously scanning LDV on a stationary platform has been employed. This work will discuss systematic investigations using a continuously scanning LDV to obtain field data in Army test lanes.
