In this study, we propose an integrated method which combines fringe projection and digital
image correlation (DIC) method into one optical system for 3-dimensional displacement …

A novel method using a charge-coupled device (CCD) camera is developed to measure 3-D
rigid-body displacement of an object. This method combines fringe projection and digital …

Study of the stress–strain state of structural materials using an optical-digital speckle
correlation (ODSC) method and digital image correlation (DIC) technique are discussed in …

The optical speckle–displacement correlation technique (OSDCT) is proposed for study of in-
plane speckle displacements. The joint transform correlator architecture is used to evaluate …

The optical speckle-displacement correlation (OSDC) technique was developed to increase
the reliability of surface displacement field recovery near stress concentrators. The …

This paper proposes an optical speckle-correlation method for plotting displacement and
strain fields on the surfaces of samples of structural materials. The method is implemented …

A technique has been proposed for the measurement of tilt of a diffuse object using speckle
fanning in a photorefractive BaTiO3 crystal. Free space geometry has been used for …

A simple 3-D displacement measurement method using a photorefractive interferometer is
proposed and experimentally demonstrated. A photorefractive crystal attached to the sample …

Speckles are a three‐dimensional self interference pattern formed by a large number of
random coherent waves. This results in a granular structure in free space or can be …
