Remarks on Residual Stress Measurement by Hole-Drilling and Electronic Speckle Pattern Interferometry [PDF]
The Scientific World Journal, 2014 Hole drilling is the most widespread method for measuring residual stress. It is based on the principle that drilling a hole in the material causes a local stress relaxation; the initial residual stress can be calculated by measuring strain in ...

Dual‐Modal Sensing Skin Adaptive to Daylight, Darkness, and Ultraviolet Light for Simultaneous Full‐Field Deformation Measurement and Mechanoluminescence Responses [PDF]
Advanced Science, Volume 12, Issue 2, January 13, 2025.A dual‐modal sensing skin for deformation visualization is developed by integrating mechanoluminescence and digital image correlation techniques. It functions effectively under various lighting conditions, such as daylight, complete darkness, and UV irradiation.

Combined denoising filter for fringe pattern in electronic speckle shearing pattern interferometry [PDF]
, 2015 We propose an effective image denoising filter that combines an improved spin filter (ISF) and wave atoms thresholding (WA) to remove the noise of fringe patterns in electronic speckle shearing pattern interferometry.

Phase-sensitive interferometry of decorrelated speckle patterns [PDF]
arXiv, 2019 Phase-sensitive coherent imaging exploits changes in the phases of backscattered light to observe tiny alterations of scattering structures or variations of the refractive index. But moving scatterers or a fluctuating refractive index decorrelate the phases and speckle patterns in the images.
