Finite element model updating from full-field vibration measurement using digital image correlation
TL;DR: In this article, the shape features of the full-field mode shapes of a composite panel are measured by a DIC system and predicted by a finite element (FE) model, which is then modified and updated.

Frequency response functions of shape features from full-field vibration measurements using digital image correlation
TL;DR: In this paper, an adaptive geometric moment descriptor (AGMD) is proposed to extract shape features from a series of full-field transient responses under random excitation, and the obtained shape features are demonstrated to be succinct and efficient.

TL;DR: In this article, a number of vibration mode shape measurement techniques are described in which the measurement point of a laser Doppler vibrometer (LDV) is continuously scanned over the surface of a sinusoidally excited structure.
Measuring area mode shapes with a scanning Laser Doppler Vibrometer
TL;DR: In this paper, a method of correcting mode shapes measured on vibrating shells, where the vibration may be assumed perpendicular to the surface, is described, and the mode shape may also be recovered as polynomial coefficients from a set of parallel straight-line scans, or by applying different-frequency sinusoidal x, y deflection inputs (Ω x and Ω y ) to the measuring laser beam.
