Abstract
An all fiber optic multi-axis laser vibrometer system has been constructed for measurements associated with structural acoustics research. This unique experimental capability was developed to allow the measurement of full 3D velocity vectors of both the interior and exterior of a structurally complex submerged cylindrical shell. The system consists of two laser vibrometers positioned by scanning robots. The design of this system as well as some preliminary measurements will be discussed.
