One flexible measurement system for academia
The EduDIC is a Digital Image Correlation (DIC) measurement systemdesigned as an entry-level, low-cost, academic training tool to assist tuition ofexperimental solid mechanics and materials testing.
This easy-to-use system gives academic instructors & students the ability
to perform optical DIC measurements for research, workshop & laboratory
exercises.
The EduDIC utilizes the full potential of Istra4D with no limitation in modular
functionality, allowing unrestricted measurement data to be acquired quick &easy and correlated with high accuracy & precision.

Complete & fully equipped with minimum hardware

The EduDIC is a complete & fully equipped measurement system suppliedwith one Laptop PC and minimal hardware components, thus making setup
quick and easy. The system operates in master/slave triggering mode, which
is a special configuration that does not require connection to an external DAQ
controller. Cameras only need to be connected to one another (for triggering)and to the Laptop PC (for data & power) – and that’s all!
Measurement performance of the EduDIC system is harnessed using the technology of USB3 Vision. Up to two, 2.3 Mpx (1920 x 1200 px), CMOS cameras canbe used which are capable of operating at a maximum frame rate of 166 Hz, atfull resolution, with unrestricted recording capacity.

Setup of the EduDIC system

Measure & test for a large scope of material testing applications
The EduDIC is a flexible & adjustable measurement system whereby thecameras may be aligned & moved freely on the mounting bar. As such, users
can utilize different stereo-angles and/or baseline distance for better in-planeor out-of-plane, accuracy. Possible material testing applications include; simple,
quasi-static tension, compression, buckling, bending, and fracture mechanic
testing.
The EduDIC incorporates a standard 25 mm fixed focal length lens withstandard Field-of-View (FoV) of up to a 200 mm (H) x 125 mm (V) at a Distanceto-Object (DtO) of 470 mm.

Istra4D Software Features
Modular Software with a Workflow Optimized for DIC
Istra4D is completely modular software giving users full flexibility
in the module selection for a required measurement application.
It allows users the possibility to expand & upgrade the capabilityof the Istra4D software if and when, the application scope of DIC
testing expands.
The software is designed to be used specifically to do Digital Image
Cor-relation (DIC). It is one software platform that is designed foran optimum user workflow experience for performing, complete
DIC measurements from start to finish. Istra4D incorporates theentire measurement DIC workflow from hardware activation,
imaging acquisition, correlation evaluation, post-processing visualization, and application scripting all in one software.
