E-VID consists of digital camera, pulg in board, and software that uses optimized 2-D algorithms to provide real-time displacement and strain data for mechanical testing. Think of E-VID 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. Real-time analog output is available for strain controlled tests with a completely noninvasive strain measurement method. Special strain control options are needed to conver this into a strain control application with our servocontroller.
