Full field optical techniques for Non-Destructive Investigation (NDI) in aerospace and automotive

Full field optical techniques for Non-Destructive Investigation (NDI) in aerospace and automotive

Description of the activity

Within the study of advanced materials such as composites, hybrid and metal alloys, with applications in technologically strategic areas (aerospace, automotive and so on), the possibility of non-destructive structural analysis, detection of damages, imperfections and the study of mechanical dynamics is a determining factor. The diagnostic and inspection optical techniques are a consolidated but in continuous development tool that combines sensitivity, speed and scalability of the measurement even at full field. Optical techniques, such as Digital Holography, Electronic Speckle Pattern Interferometry, Shearography and Digital Image Correlation are suitable to reveal barely visible damage, residual stress or cracks at the beginning stage and in general they are suitable for quality control on conventional and innovative materials. They meet the industrial request to improve the overall quality and to reduce the costs allowing a smart structural characterization of advanced materials and a fast, full field inspection also directly on the industrial products.
