In addition, NDT can also identify situations that could potentially lead to critical failures. Specifically, NDT by optical methods have become popular because of their noncontact and noninvasive nature. Shearography is a highresolution optical NDT method for identification and characterization of structural defects in components and has gained wide acceptance over the last decade; however, as a drawback, shearography cannot locate the position of defects in 3D. To overcome this limitation, we are combining shearography with Fringe Projection (FP). FP allows highspeed, noncontact, fullfieldofview 3D shape measurements to enable the 3D localization of detected defects on the objects of interest. We show preliminary results obtained by combining shearography and FP to perform NDT in specific aerospace structures.Read More
