技术概述 Technology Overview


Vic-Gauge uses our optimized 2-D and 3-D correlation algorithms to provide real-time displacement and strain data for mechanical testing. Think of this tool as a set of virtual strain gauges: Data can be retrieved for multiple points and plotted live against analog load inputs. Results are saved for every analyzed point, and full images may be saved for full-field analysis in Vic-2D or Vic-3D.

该系统通过用模拟信号来实时输出测量数据,实现了以完全无损的应变测量方法来驱动和控制试验。 Vic-Gauge™可以测量从50个微应变到5000%以上的任意应变和位移,试件尺寸从小于5mm到大于 5m不等。

Real-time analog output is also available, allowing strain controlled tests with a completely noninvasive strain measurement method. Vic-Gauge™ can measure arbitrary displacements and strains from 50 microstrain to 5000% strain and above, for specimen sizes ranging from <5mm to >5m.

Because the setup is simple, requiring only a single camera imaging the specimen, the Vic-Gauge™ system can easily be integrated with almost any tensile test frame. No special illumination or lasers are required.



We offer complete turn-key measurement systems for a wide range of deformation and strain measurement tasks. Our systems and analysis software are designed with the user in mind and are simple to set-up and operate. Some of the features of our systems include:

We also provide components as well as custom measurement systems for demanding applications including high temperature, higher speeds, and very small- or large-scale samples. Please contact us at if you would like to discuss your applications.




Our Vic-Gaugesystem is widely used for material testing of compliant materials such as polymers, rubber or biological tissue. The system is capable of real-time strain measurement and can be interfaced with standard tension/compression test frames and controllers. For high strain rate testing, we offer Vic-Gaugesystems capable of 100,000 samples per second (post-processing).
