Quality assessment of speckle patterns for digital image correlation
Digital image correlation (DIC) is an optical-numerical full-field displacement measuring technique, which is nowadays widely used in the domain of experimental mechanics. The technique is based on a comparison between pictures taken during loading of an object. For an optimal use of the method, the object of interest has to be covered with painted speckles. In the present paper, a comparison i...
متن کاملOptical Measurement of Deformation Fields and Surface Processes with Digital Speckle Correlation
This thesis presents a detailed investigation of Digital Speckle Correlation (DSC) as a tool for the measurement of three-dimensional deformation fields and surface processes, i.e. changes in the microstructure of the surface. The method is based on a detailed analysis of the changes in the speckle field that is scattered from a laser-illuminated rough surface, using digital image processing. T...
متن کاملDigital Image Correlation combined with Electronic Speckle Pattern Interferometery for 3D Deformation Measurement in Small Samples
The small size of mesoand microelectromechanical systems (MEMS) devices presents several challenges for full-field deformation measurements. A hybrid system combining Digital Image Correlation (DIC) for in-plane deformation and Electronic Speckle Pattern Interferometry (ESPI) for out-of-plane deformation measurements has been developed for working with these small size scales. Measurement of th...
متن کاملA Novel Sub-pixel Measurement Algorithm Based on Mixed the Fractal and Digital Speckle Correlation in Frequency Domain
The digital speckle correlation is a non-contact in-plane displacement measurement method based on machine vision. Motivated by the facts that the low accuracy and large amount of calculation produced by the traditional digital speckle correlation method in spatial domain, we introduce a sub-pixel displacement measurement algorithm which employs a fast interpolation method based on fractal theo...
