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

Composite materials have seen widespread use in the aerospace industry and are
becoming increasingly popular in the automotive industry due to their high strength and low …

The field of optical metrology offers a wealth of both practical and theoretical
accomplishments, and can cite any number of academic papers recording such. However …

Abstract Three dimensional (3D) displacements, which can be translated further into 3D
strain, are key parameters for design, manufacturing and quality control. Using different …

Conventional methods of quadrature phase-shifting holography require two holograms and
either intensity distribution of the reference wave or that of the object wave to reconstruct an …

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 …

This paper presents a simple spatial phase shift shearography based on the Michelson
interferometer. The Michelson interferometer based shearographic system has been widely …

This paper presents a spatial phase-shift digital shearography system based on a modified
Michelson Interferometer, which is capable of measuring out-of-plane deformation and its …

A new shearography configuration was developed to simultaneously acquire images of a
specimen in three different shearing directions, the proposed configuration is capable of …

A novel differential phase detecting surface plasmon resonance (SPR) sensor based on
white-light spectral interferometry is presented. Our proposed scheme employs a white-light …
