Digital Image Correlation (DIC) is a non-contact, full-field technique that provides a reliable approach for studying the modal parameters of rotating structures. When combined with Operational Modal Analysis (OMA), it enables the identification of these parameters directly from the frequency content of the structural response, without requiring knowledge of the applied force. This makes DIC and OMA particularly valuable for analyzing rotating components, such as turbine and compressor bladed disks in aeronautical engines, under operational conditions. Despite its effectiveness, applying DIC to rotating structures presents unique challenges. Traditional DIC algorithms require small inter-frame structural motions, making incremental DIC necessary for analyzing rotating structures.
