High-Speed Cameras Help Digital Image Correlation Show Its Strength

By Vision Research, Inc.

Digital image correlation (DIC) is an optical measurement technique that allows full-field analysis of a material’s or structure’s deformation, displacement, and strain. The popularity of the technique is growing, especially in the aerospace, defense, and automotive industries where DIC is used to test the strength and load response of various parts and materials. This paper discusses how high-speed cameras and various software packages are helping DIC expand into new applications while also ensuring the technique delivers quality quantitative data.
