Hi-Tech DIC Video Extensometry

Is the accurate measuring of strain and displacement critical for your engineering or construction projects?
Then ALPHA DIC is ideal for you!

X-Sight’s Alpha DIC software, developed by X-Sight, is an industry-recognized and effective instrument for optical measurement and analysis of deformation, vibration, and strain of virtually any material or structure. Alpha DIC SW is founded upon the digital image correlation (DIC) measuring technique. DIC is a cutting-edge machine vision technology based on the comparison of optical images acquired from moving or deforming objects which results in obtaining displacement vectors recorded object’s surface at an exceptionally high spatial subpixel resolution.


Alpha DIC SW processes images acquired by a wide selection of our specialized video extensometers and measuring systems, so it is possible to deliver customer-specific measuring instruments optimized for the desired experiment design or material testing process. Our video extensometers are suited for diverse static and dynamic testing applications, including tensile, compression torsion, shear, and flexural tests. 



Allows for measurement of axial strain in real-time. In addition to the elementary measuring probes such as Point probe and Line probe, the Alpha Axial Strain measurement module includes the Extreme Line probe that divides the length of the specimen into multiple precisely defined gauge segments and detects the necking area. This function provides an advantage over conventional single-position measurement, wherein a rupture outside the gauge length area causes test invalidity.

Allows for measuring of transversal strain in real-time. In addition to the elementary measurement probes such as Point probe and Line probe, the Alpha Transversal Strain measurement module includes the Trans Line probe with the edge detection feature. The Trans Line offers single or multiple line width measurement. This is an advantage over the conventional single-position measurement. All lines can be averaged for a precise Poisson’s ratio reading. The transversal module does not support axial strain measurement.

A bundle of Axial and Transversal modules.

Allows for measurement of angular twist on cylindrical specimens in two positions. Usable in static and dynamic applications.

This module is an extension and works only with the A or T modules.

This module unlocks a remarkably efficient tool for processing of previously recorded tests with sub-sequent playback and data export. Each real-time measurement method can have multiple offline records with a custom probe layout. Post-Process is an optimal solution for measurement of unique or expensive specimens and components.

This module provides a strain or displacement distribution map, thereby enabling to obtain maximum available data from each experiment. This feature surpasses other technologies on the market. It helps users all over the world not just to improve the understanding of their experiments, but thanks to an easily interpretable output, also to sell their results effortlessly.

DIC Area includes the full Post-Process module.

Alpha 3D DIC combining DIC with stereo vision, can measure the 3D displacement field and surface strain field of 3D objects.

Enables real-time import of external values concerning force, motion, or temperature as an analog or digital signal into Alpha. Useful mainly for post-processing or measurements taking place outdoors.

This module is designed for crack length measurement of compact tension (CT) or double cantilever beam (DCB) specimens. Line probe function is included in the CL module. Line probe enables crack opening measurement providing results comparable to conventional devices.

While a full-field strain distribution via DIC Area analysis needs post-processing due to a high number of computational points, the Line Strain Distribution provides a colourful strain visualization feature during real-time measurement.

An advanced feature for measuring specimens with an outside layer creating fragments that eventually fall off. A typical application is the tensile testing of reinforcing steel bars with a layer of oxide or rust.

Video Extensometry Application



Alpha 3D DIC SW takes advantage of combining DIC with the use of two or more cameras, allowing to measure the 3D displacement field and surface strain field of 3D objects. Alpha DIC is ideal for testing the mechanical behavior of materials. Alpha DIC provides strain maps and visualization of the response of a component or structure under various loading conditions. It allows to verify and refine finite element analysis models of complex geometries.


Alpha DIC software is modular due to a broad selection of particular features, which means that it can serve in various configurations ranging from a lean and straightforward uni-axial video extensometer to an advanced full-field strain mapping analysis post-processor. The Alpha DIC is intuitive and user-friendly, emphasizing the ease and simplicity of specimen preparation and system calibration, making X-Sight video extensometers an attractive option from both technical and cost-effective testing standpoints.
