Zusammenfassung
Digital image correlation (DIC) is a method of using digital images
to calculate two-dimensional displacement and deformation or for
stereo systems three-dimensional shape, displacement, and deformation.
While almost any imaging system can be used with DIC, there are some
important challenges when working with the technique in high- and
ultra-high-speed applications. This article discusses three of these
challenges: camera sensor technology, camera frame rate, and camera
motion mitigation. Potential solutions are treated via three demonstration
experiments showing the successful application of high-speed DIC
for dynamic events. The application and practice of DIC at high speeds,
rather than the experimental results themselves, provide the main
thrust of the discussion
