Optical excited Sheargraphy

OTShearoVis - big advantages with large components

  • Optical excited Shearography is a remote non-destructive test method
  • Measurement of sample deformation under load
  • Well suited for characterization of fibre composites and adhesive interfaces
  • Used in automotive, aerospace and wind energy sector
  • Application in production and maintenance
  • Compatible and extendable with other edevis excitation sources and software modules

Principle of optically excited Shearography

Principle of optically excited Shearography

Shearography with thermal excitation requires only small hardware efforts and is at the same time one of the the most versatile shearography variants. Besides a laptop and a sensor, in many cases only a halogen lamp with a dimmer is needed. Some thermal excitation methods can heat large areas in a non-contact way and thereby allow for the inspection of large structures.

Typical applications for optically excited Shearography

Stringer-verstärkte CFK Struktur

CFRP component measured with optical excited Shearography. Impact damages are revealed with high sensitivity.

CFK Monocoque Structure

CFRP monocoque with delaminations.


  • Inspection of CFRP and other fibre composites (detection of impacts, ondulations, delaminations, adhesion of inserts, inclusions, ...)
  • Inspection of sandwich components (e.g. Aluminium, CFRP, GFRP, … an honeycomb, foam, …)
  • Inspection of adhesive joints
