Paper Abstract

A novel system for using a single-point Laser Doppler vibrometer (LDV) to measure surface normal velocity components of non-planar targets has been developed. A description of this measurement system is presented, along with a discussion of results and relative merits compared with conventional scanning LDV systems. Data from sample measurements taken on an anti-tank landmine buried in sand are presented. It is shown that measurements of the same surface wave using this system and a conventional system can differ by as much as 75%.
