Title
An automatic scanning algorithm for high spatial resolution laser vibrometer measurements
Author
Abstract
Many structural problems, as for instance the prediction of the radiated acoustic noise from vibration data, require measurements with a high spatial resolution. An adapted instrument to perform this kind of measurements is the scanning laser Doppler vibrometer. Since the spatial complexity of the vibration patterns is usually unknown in advance, the number of scanned locations is often taken ad hoc. This implies that the amount of measurement locations can be over- or under-estimated. In this article, a method is presented to automatically determine the number and the location of the grid points to be scanned in order to model the vibration behaviour accurately enough. In particular, the method can be used to successfully find delaminated areas in composite plates (which typically exhibit local vibration behaviour). (C) 2003 Elsevier Science Ltd.
