Digital Imaging (DIC)

Optical methods for surface imaging are an extremely important non-intrusive tool in today’s investigations of complex structures and advanced materials. It is an intuitive approach to the measurement and analysis of the mechanics of materials, providing accurate numerical data together with qualitative visual feedback.

Surface imaging allows the user to acquire data regarding shape, deformation, and strain of components, without the need for complex calibration. Important parameters such as crack top propagation, crack opening, and strain derivatives are easily obtained. Single camera systems allow the quick analysis of planar deformation, and multi camera systems measure the full shape, deformation and strain of a 3D component under test. 
The wealth of information available is unprecedented.
