Laser speckle photography-one of the Laser speckle measurement methods which, recently, are used widely in various science, and engineering applications are succesfully used in the non-contact measurement of In-plaane displacement. In this study, automated measurement and analysis are tried in the laser speckle photo- graphy method using a video camera, computer control and processing, and a X-Y positioning table driven by computer controlled stepping motor. The experiment was compared with the theorecial strain and stress data from finite element method. The result showed that displacement, strain and stress can be measured more accurately and conveniently by using this approach.
