Abstract
Scanning laser Doppler vibrometer measurements are characterized by a high spatial resolution and the fact that the Structure is measured (or scanned) point by point. These measurements can be processed with the exciting generic modal parameter estimators. However, more accurate modal parameter estimates can be obtained by exploiting the spatial "smoothness" of high spatial-resolution mea sure merits. To do so, the mode shape will be represented by a generalized parametric Fourier-based model. In this contribution, this generalized parametric Fourier-based mode-shape smoother will be integrated inside the modal parameter estimation procedure resulting in a fully (spatial as well as temporal) parameterized modal model.
