The shearography tire test systems from Steinbichler Optotechnik have been developed for the non-destructive testing of new tires in R&D and quality control, as well as for the inspection of tire carcasses in the retreading industry. The technical basis of the systems is the TV shearography system.

During the test cycle, a low pressure (e.g., 50 mbar pressure difference) is generated in the vacuum chamber, thereby inducing deformations which are caused by the expansion of air pockets occuring in faulty areas in a tire carcass. With the TV shearography technique - a holographic measurement method which reliably detects material deformations in the range of microns - faulty areas can be localized clearly and reproducably.

The Intact systems by Steinbichler Optotechnik have successfully proven their functionality in the worldwide car-, truck-, and aircraft industries, as well as in the Formula 1 racing tire business.
