In this application video, two high-speed SpeedSense cameras are used to measure the displacement of a PC ventilator fan in operation. Within the correlation evaluation, subsets/facets are selected and tracked as discrete points throughout the measurement series. All found points are highlighted in the table as green with the respective back projection residuum value (accuracy indicator). Red indicates that the point cannot be found within the specified tolerance. Users can shift points to another locations, using the accuracy indicator and the correlation is then updated automatically for the shifted point. The trajectory of the point can also be seen. In this example, both discrete point (marker) data and full-field DIC data are correlated and exported together to the graphical visualization.
