Optional full-field test After measuring the module, full-field displacement and strain measurement can be achieved. UHPC tensile mechanical properties test UHPC high-temperature tensile test Visual Strain Gauge-The standardized high-speed measurement series adopts monocular 3D DIC technology, and the high-speed DIC test can be completed only with a set of high-speed camera and mirror head, which greatly reduces the system cost. The optical path has a wide range of adaptability to match the high-speed cameras and lenses commonly available on the market. Small size, easy to narrow space and small field of view measurement, suitable for Hopkinson rod impact, high-speed vibration and other tests。 Application Cases Visual strain gauge gauge Three point bending test of concrete beam Laser focus Fast and efficient High precision High repeatability accuracy Concrete gradient ECC four point bending test Strain gauge mode Real-time measurement feedback Standardized measurement No calibration required The world's first monocular 3D DIC technology The visual strain gauge is a deformation measurement system based on monocular 3D DIC technology, which can realize 3D full-field strain measurement with a single camera. The image acquisition of the specimen loading process can be realized through the measuring head of the strain gauge. The strain gauge software can complete the calculation of the image and output the measured deformation result. Concrete pouring cylinder co
