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

Television holography (TVH) can be defined asthe family of optical measurement
techniques based on the electronic recording and processing of holograms'. Image-plane …

Optical Methods of Measurement: Wholefield Techniques, Second Edition provides a
comprehensive collection of wholefield optical measurement techniques for engineering …

This study focuses on the development of a complementary fatigue crack-tip evaluation
approach with multiscale optical techniques with different resolutions. A middle tension (MT) …

A novel inverse identification method using only a single tensile specimen for obtaining four
anisotropic elastic constants of fiber reinforced composites sheet is proposed in this study …

Initiation of failure under three-point bending was observed in sandstone specimens with
and without a stress concentrator. Acoustic emission (AE) and electronic speckle pattern …

A fully automatic speckle metrology technique is developed. Two speckle patterns of a
specimen, one before and one after the specimen deformation, are captured by a video …

Optical techniques have been applied to the measurement of solid deformations in many
instances. Practical difficulties with a particular technique can be overcome, in some …

Electronic speckle pattern interferometry (ESPI) is a wholefield non-contact optical metrology
technique for displacement measurement, based on the optical physics of surface …

We report on a digital speckle pattern interferometer that applies a binary diffractive optical
element (DOE) to generate double illumination and radial in-plane sensitivity. The …
