Digital Image Correlation (DIC) technology leverages binocular or multi-camera stereo vision and digital speckle matching algorithms to enable non-contact, full-field, and multi-scale synchronous measurement of 3D displacement and strain, even under extreme operating conditions. The XTOP3D XTDIC series encompasses models designed for microscopic, standard, high-temperature, high-speed, and ultra-large field-of-view applications, providing a one-stop solution to meet the needs of academic research, industrial reliability verification, and rigorous mechanical testing for high-end equipment.
