Deformations
 
Many optical technologies are proposed for the measurement of surface deformation  :

  • speckle interferometry provides measurement accuracy of 0.1 micrometer
  • CorreliSTC ® imaging technique allows easy access to 3D displacement mapping.
Speckle interferometry
The speckle interferometry is an imaging technic that uses laser light and can visualize and quantify the movement on the surface of an object between two states. It is used in laboratory and in the factory.  Speckle interferometry
Correli STC ®
CorreliSTC ® is the combinaison of image correlation technic and fringe projection. Simply using white light, it provides access to maps of 3D displacement of the surface of a part.  Correli STC ®
