Abstract

In this paper, a novel methodology is introduced to measure the
vibration behaviour of structures using a scanning laser Doppler
vibrometer. The laser beam continuously scans the surface of the device
under test, while a broadband excitation signal is applied. In
particular, the method developed adapts itself automatically to the
(spatial) complexity of the vibration patterns and to the (frequency
domain) modal density. The measurement time is compared with classical
measurement procedures.
