Shearography, a nondestructive optical measuring method on basis of the speckle interferometry, is sensitive for local surface strain caused by defects in the volume of the component as a result of load changes. This sensitivity enables the detection of defects or anomalies within components or inspection objects. Load changes can be caused by changes in temperature or pressure or by vibrations.
Detection of material defects:
Delaminations, Kissing bonds, Dis bonds, impact defects, drapery, etc.
GFRP, CFRP, Honey Comb, GLARE, foams, laminates, composites, etc.
Aerospace, automotive industry, wind energy, etc.
Quality control for high-performance composites
Automated shearography system for helicopter rotor blades
NDT for glued (oder bonded) sandwich structures:
Inspection of rotor blades (wind power plants)
