X-Sight DIC Software Modules
AX - Axial Strain
Basic UI and mandatory module. 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.

Extreme Line Probe
TR - Transversal Strain
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.

TO - Torsional
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.
Torsion Line Probe
PP - Post Process
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.

LVD - Line Value Distribution
While a full-field strain distribution via DIC Area analysis usually requires post-processing due to a high number of computational points, the Line Value Distribution module provides a colourful value visualization feature that is more feasible during real-time measurements. It is supported by most types of probes that are divided to line segments, specifically strain distribution for Extreme, ROD and Bend Lines, including an additional choice of Deflection or Curvature for Bend Lines.
