We offer innovative non-destructive technologies


An efficient non-contact optical technique


Shearography is an interferometric technique that enables the measurement of the out-of-plane displacement gradient. The technique has to be associated with a mechanical or thermal loading mean : heating using an optical source, vacuum,..


The object to be measured is mechanically or thermally loaded while recording is done with the shearography equipement. Defects appear as a local gradient in the displacement map (in the micrometer range).

An optical technology

No contact with the object

No surface preparation

A few seconds recording time

Adapted to gluing defects, delamination

Post-processing and data archiving possible
