High Speed Digital Image Correlation Techniques 2006-01-0528

Image Correlation technique has been proven to be a flexible and useful for deformation analysis. It’s a robust method for measuring full-field absolute displacement and strains. In this paper we describe a new Digital Image Correlation (DIC) system, where all components (hardware and software) are fully integrated in order to build a self-contained measurement system. Due to a modular structure for hardware components as well as for the software in combination with high speed cameras this can be used for investigations on transient events.
The calibration of a DIC system is the most important action, which is needed to generate accurate results. Therefore we describe the procedure, which allows an easy to use, reliable and fast calibration as an integrated part of the system.
Results of measurement performed on a vibrating membrane and a tensile test sample are show typical features of the system.
