摘要

In this article a generalized regressive Fourier series approach is shown which does not suffer from the so-called leakage effects prone to frequency domain approaches. This parametric approach will be used to tackle a number of optical techniques. Due to the fact that the technique offers an approximation and not an estimate of the data, it is possible to reduce the spatial data of operational mobility shapes measured by e.g. a laser Doppler vibrometer (LDV). It also allows a reduction of measurement time of this former technique. The LDV will also be used to visualize and localize acoustic sources.
