Paper Abstract

The need to predict the dynamic behavior of a structure is of paramount importance in many engineering applications. To achieve this goal a certain number of measurements of the structure under study are needed. Unfortunately, not all the measuring problems can be solved with traditional techniques: on small and light structures the mass loading effect of the instrumentation can yield to incorrect estimation; similarly, in case of high temperature surfaces and magnetically or electrically noisy environment the use of normal sensors, like accelerometers, might be unmanageable. The use of a non-contacting technique, like the Laser Doppler Vibrometer seems to be a way to overcome efficiently and elegantly these problems.
