In the last few decades, there has been a surge of research in the area of non-contact
measurement techniques. Photogrammetry has received considerable attention due to its …

Shearography is a full-field speckle interferometric technique used to determine surface
displacement derivatives. For an interferometric technique, shearography is particularly …

This paper presents the activities in the field of shearography in chronological order and
highlights the great potential of this holographic measurement technology. After a brief …

Fiber imaging bundles have been investigated for use in endoscopic optical coherence
tomography (OCT) systems, to obviate the requirement for scanning components within the …

Full-field in-plane strain measurement under dynamic loading by digital shearography
remains a big challenge in practice. A phase measurement for in-plane strain information …

Laser speckle is a kind of noise in triangulation displacement measurement. It's
meaningless to restrain speckles when the imaging light spot is so weak that facular image …

A non-contact rotational thermal-structure deformation measurement system based on
digital image correlation (DIC-2D) technology was proposed and established to measure in …

Shearography is an optical technique that relies on interference of laser speckle patterns to
visualise variations in surface strain. As it provides full-field measurements and is …

Quantitative shearography applications continue to gain practical importance. However, a
study of the errors inherent in shearography measurements, related to calibration of the …

Laser shearography is a powerful optical tool that is able to directly measure the
displacement derivatives using interferometric effects. Stroboscopic shearography provides …
