Acceleration sensors are commonly used for measuring the vibrations of structures.
However, these contact-type sensors cannot be installed in some areas, such as on objects …

Abstract Experimental Modal Analysis (EMA) allows to assess the dynamical properties of a
mechanical component or structure by estimating the modal parameters. Whereas EMA is …

High-speed camera measurements are increasingly being used in modal analysis to
instantaneously measure full-field structural responses by extracting the displacement …

Instantaneous full-field displacement fields can be measured using cameras. In fact, using
high-speed cameras full-field spectral information up to a couple of kHz can be measured …

Abstract Digital Image Correlation (DIC) is a non-contact full-field image analysis technique
which allows to retrieve strains and displacements in three dimensions at the surface of any …

Modal parameters characterize how tools vibrate. Correct evaluation of modal parameters
depends on how signals are sampled. Since tools can vibrate with frequencies of up to …

Abstract Experimental Modal Analysis (EMA) has developed into a major technology for the
study of structural dynamics in the past several decades. Through Experimental Modal …

Abstract Three-dimensional (3D) vibration measurements are important for monitoring
rotating structures in order to reproduce the directional displacements of vibration signals …

Digital image correlation (DIC) is a non-contacting, optical method for measuring full-field
displacements. Recently, there has been interest in DIC as a tool for experimental modal …

Vibration analysis is one of the most widely used methodologies for structural health
