Temporal Analysis of Speckle Images in Full-Field Interferometric and Camera-Based Optical Dynamic Measurement

Photonics
Vibration measurement is crucial in fields like aviation, aerospace, and automotive engineering, which are trending towards larger, lighter, and more complex structures with increasingly complicated dynamics. Consequently, measuring a structure’s dynamic

Determination of fracture mechanics parameters on a base of local displacement measurements

Fracture and Structural Integrity, 2013
New experimental technique for a determination of the stress intensity factor (SIF) and T-stress values is developed and verified. The approach assumes combining the crack compliance method and optical interferometric measurements of local deformation ...

Measuring micro-displacements of specular surfaces using speckle interferometry

, 2018
The displacement field of an object surface can be measured by using speckle interferometry. This technique is based on the phenomenon of laser speckle and consists in correlating speckle interferograms taken after and before the deformation of the ...

Correlation Between Intensity and Phase in Speckle Pattern Interferometry

, 2000
We simulate the field distribution of a fully developed speckle pattern (SP) due to diffusion of laser light from a remote rough surface. We show that, under some circumstances, the phase fluctuation and the logarithm of intensity are linked by Hilbert ...
