High-Speed, Non-Contact 3D Displacement and Strain Measurement
The Digital Image Correlation (DIC) High-Speed Strain Measurement System is an advanced optical measurement solution designed to capture and analyse material deformation under high-speed and extreme loading conditions.
The system integrates two high-speed cameras, a synchronisation trigger, RVM measurement software, calibration plates and a dedicated graphics workstation to deliver precise, real-time measurement of 3D coordinates, displacement and strain.
Using advanced digital image correlation technology, the system captures full-field deformation and strain data without physical contact with the specimen. This makes it particularly suitable for analysing material behaviour during impact testing, rapid deformation and other high-speed dynamic events.
