Digital Image Correlation (DIC) is a non-contact optical technique used to measure full-field surface deformations and strains by analyzing images captured during mechanical tests or experiments. High-speed cameras provide the necessary frame rates to capture fast events, enabling researchers to accurately track surface displacements and deformations in real-time. By analyzing the sequential images captured by high frame rate cameras, DIC software can precisely quantify strain and deformation patterns, providing valuable insights into the mechanical behavior of materials and structures under various conditions. This technology finds widespread use in industries such as aerospace, automotive, biomechanics, and civil engineering, where understanding the performance of materials and components is crucial for design optimization and quality assurance. In essence, high-speed cameras serve as the backbone of DIC systems, facilitating high-resolution measurements and advancing our understanding of structural behavior and material properties.
