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
Development of equipment for a given need
