Abstract

A novel method utilizing a correlation-based approach for high-resolution velocity measurements is presented. Existing techniques for high-resolution velocity measurements use the modal velocity for estimating the displacement, and a wealth of information stored in the cross-correlation is discarded. A background study on optimizing the measurement accuracy of PIV in estimating the displacement and the gradient of the flow is presented. We introduce a novel method, which can yield velocity measurements that have infinite resolution, and the velocity gradient that is directly computable.
