The Laser Shearography System (Q-800) is a fully portable and compact measuring system for Non Destructive Testing that provides fast and accurate information about the inside quality of different materials.
The NDT-System can detect defects, delaminations, disbonds, kissing bonds, wrinkling, impact damage and many more. The turn-key optical system is non-contact and full field and will work on such materials as fiber reinforced plastics, laminates, honeycomb, foam, wood, metal and Glare.
The Q-800 shearography system consists of a miniaturized shearography sensor with integrated high-resolution CCD and variable computer controlled shear optics. Illumination is provided by an integrated diode laser array and the whole system is controlled from a laptop PC using the new Istra 4D software platform.
Further image processing is also available for export and reporting. Typical inspection times are 10 to 30 seconds and can cover areas from a few mm² up to several m² in one inspection.
Measurement Principle
The highly sensitive interferometric technique will measure microscopic surface deformations caused by internal flaws when a small loading is applied to the object. This can be done using thermal, pressure, vibration or mechanical excitation.
The results are displayed live as the material responds to the excitation and are easily interpreted by the operator.
