During operation, wind turbine blades are subjected to varying loads, making them vulnerable, reducing performance, and increasing mechanical failures. Furthermore, blade maintenance is both time-consuming and costly. Optical methods, such as DIC, are attractive to measure deformations on this kind of structures because they do not require electrical wiring, they avoid mass loading effects, and they can be easily configured to measure large test articles. In this paper, a novel optical technique based on DIC is described for performing full-field measurements by using contact-less techniques. In this paper, the possibility of using low speed cameras DIC to perform modal analysis and to validate and update finite element models is investigated, testing a scaled wind turbine blade in different conditions. The results obtained with DIC are compared with the ones obtained with accelerometers and correlated with the numerical solutions.
