Speckle photography is an advanced experimental technique used for quantitatve
determination of density, velocity and temperature fields in gas, liquid, and plasma flows …

Because of their nonintrusive, real-time and full-field features, holographic interferometry [1,
2, 3, 4, 5, 6, 7, 8, 9, 10] and speckle metrology [11, 12, 13, 14, 15][16, 17, 18, 19] have …

An experimental scheme of digital speckle pattern interferometry using two electromagnetic
shutters and a three-frame color image board is presented to measure two in-plane …

Inasmuch as current fringe analysis techniques used in digital speckle-pattern interferometry
(DSPI) yield a phase map modulo 2π, phase unwrapping is the final step of any data …

Deformation study of curved engineering and technical surfaces, such as pipes and
pressure vessels, has gained much importance in the recent past. Speckle interferometric …

We have developed a unique optical interferometric technique for deformation analysis and
have applied it to tensile analyses of aluminum based samples. Using a recent theory of …

A phase-shifting electronic speckle pattern shearing interferometer with a very simple
shearing device is proposed. Two partially reflective glass plates are used to introduce the …

In this report, design and assembly of a simple, easy-to-make and low-cost piezoelectric
actuator (PZA) with one degree of freedom for application in phase-shifting interferometry is …

The introduction of a pulsed laser into an electronic speckle-shearing pattern interferometer
allows high-speed transient deformations to be measured. We report on a computerized …

A preliminary study of the application of speckle shearographic methods in the
nondestructive inspection of the curved surfaces of soft tissue phantoms is presented. An …
