Digital Image Correlation: Non-Contact Surface Deformation Measurement
Digital Image Correlation (DIC) is a non-contact optical technique that measures full-field displacements and strains by correlating digital images of a specimen’s surface captured before and after deformation. Techniques include 2D DIC, 3D DIC, Triangulation-based DIC, Stereo DIC, and Motion Amplification DIC. Applications involve strain measurement, damage analysis, fatigue testing, and structural health monitoring. Software…
