Deformations
 |
Several optical technologies are proposed for measuring surface deformation :
- speckle interferometry offers precision of 0.1 µm in measurement
- CORRELI 3D is a white light imagery technique giving easy access to 3D displacement maps
Speckle interferometry
Speckle interferometry is an imagery technique using laser light and displaying and quantifying movements at the surface of an object between two different states. It is used in the laboratory and on site. 
Correli 3D
CORRELI 3D is the association of the image correlation technique and of fringe projection. Using simply white light. It provides access to 3D displacement maps on the surface of a part.
