The laser Doppler vibrometer (LDV) has been recognized as the instrument of choice when non-contact
vibration measurements are required, and is also capable of acquiring measurements with high spatial detail; one
only need redirect the laser beam via computer controlled mirrors to acquire data for additional measurement
points. However, since most LDV systems are only capable of acquiring data for one point at a time, testing times
tend to be quite long. This problem is formidable for structures with low natural frequencies, such as aircraft,
space structures or civil structures, which would require prohibitively long testing times if LDV were used. One
