Monocular 3D Video Extensometer
Haytham DIC continuously acquires the entire test process — not only recording results at key stages, but preserving the whole timeline of damage initiation, propagation and evolution.
Haytham's monocular 3D DIC, based on single-camera 3D reconstruction and DIC algorithms, continuously acquires and analyzes surface deformation features, obtaining 3D displacement fields and full-field strain distribution of soil during tension without contact.
Through continuous image acquisition and correlation analysis of the block surface, Haytham DIC obtains full-field displacement and strain distribution during compression without touching the specimen.
Through optical imaging and correlation analysis, Haytham DIC continuously tracks specimen surface features, obtaining full-field displacement and strain distribution during bending without contact.
In structural dynamics experiments, the research team used Haytham's monocular 3D high-speed DIC for full-field vibration measurement of a large-scale structural scale model. High-speed cameras were placed outside the model, capturing 3D motion information of the structure surface from multiple views synchronously without physical contact.
Haytham integrates DIC full-field strain measurement with infrared thermal imaging under unified calibrated coordinates, observing temperature fields and strain/displacement fields simultaneously in the same coordinate system and time axis — extending characterization from a single quantity to multi-physics collaborative analysis.
The virtual strain gauge is based on DIC algorithms rather than a physical sensor. The system computes high-precision displacement/strain from images before and after loading, creating virtual measurement points at any location on the specimen surface, with results available in real time or via post-processing.
Haytham's visual microscopic strain measurement system uses DIC to obtain minute displacement and full-field strain distribution of earphone cables during repeated bending, accurately locating strain concentration and fatigue weak regions — a reference for cable structure optimization, life assessment and failure analysis.
As a core part of automotive safety evaluation, how the steering wheel column behaves at the moment of impact directly affects driver safety. How does Haytham's monocular 3D high-speed vision strain gauge help optimize structural safety?
