Monocular 3D Video Extensometer
In tensile testing of glass fiber materials, Haytham's monocular 3D video extensometer was used. The specimen was clamped in the tensile machine; the extensometer captured surface deformation of the glass fiber specimen during tension via a single camera, analyzing images with DIC to compute strain distribution in real time.
In reactor vibration testing, the customer needed precise measurement of vibration frequency and amplitude under different operating conditions, especially the surface strain distribution. Given the reactor's large size and complex test environment, traditional contact sensors may not provide comprehensive, accurate data — a non-contact device with high dynamic response was needed.
Hopkinson impact testing of small specimens requires high precision and high-speed response to capture strain changes within extremely short times. Traditional strain measurement equipment for small specimens and high-speed dynamic tests usually requires complex multi-camera systems, increasing equipment cost and demanding more lab space and arrangement.
In wall panel projectile testing, the customer needed precise measurement of transient deformation and strain distribution under projectile impact. With the extremely high strain rate at impact, the equipment must capture the high-speed dynamic process in real time and provide full-field strain data for comprehensive analysis of panel deformation behavior.
In fatigue life verification of propeller blades, traditional strain gauges are limited by difficult curved-surface installation, complex wiring and signal degradation under long-term vibration, making comprehensive, stable strain measurement hard to achieve. The project team therefore adopted the Virtual Strain Gauge (VSG) mode, achieving multi-point synchronized strain monitoring and life assessment of the blade surface without changing the test setup.
In high and low temperature deformation testing of the phone optical sensor, the sensor must withstand extreme temperature changes from 20℃ down to -40℃ and up to 200℃. Precisely measuring its minute deformation under these temperatures is essential to performance stability. Haytham's vision strain measurement system, with advanced DIC technology, provides a reliable solution for this test.
Haytham's monocular 3D vision strain gauge performed a dual-device single-point tracking test of railway track. By placing two Haytham instruments at key track nodes, the team achieved synchronized strain measurement of the track as trains passed.
In a study of in-situ tensile testing of plant fibers, the team used Haytham's visual microscopic strain measurement system for detailed mechanical analysis. The system recorded fiber deformation during tension in real time and generated high-precision stress-strain curves.
