Paper Abstract

Digital speckle correlation method (DSCM) is one of the most important tools for deformation measurement and fluid inspection. Definitions of the correlation coefficient, search schemes and sub-pixel estimation methods are three key problems to the development of DSCM. In this paper, various improvements in literatures concerned on these three key problems are compared and some new techniques are developed according to the comparison. An experiment using SEM images is completed to reveal the ability of micro-deformation of DSCM.
