Recent Research: More on Fringe Projection
	In the INDUCE project funded by the EU, fringe projection was used to register the shape and location of aerospace components during evaluation using non-destructive techniques such as x-rays and ultrasound. The acquisition of shape and location data in the same spatial domain as the NDT data allows the NDT data to be registered relative to the CAD model of the component. The intention was to perform NDT analyses throughout the product life-cycle from design prototypes to in-service aircraft. This part of the project was performed by a partnership of the Universities of Sheffield and Madrid, CASA-EADS and BAE Systems. At the end of the project, BAE Systems produced a video of the demonstrations performed by the University of Sheffield and BAE Systems using the Eurofighter Typhoon aircraft as the exemplar. Since the complete video is quite large (93Mb), three clips are provided below showing the use of fringe projection with NDT at three stages of the aircraft life-cycle.
In design – registration of X-ray inspection data		In manufacture – automatic inspection trajectories for the ultrasound testing of complex parts		In service – inspection on aircraft during maintenance
