Larer-ultrasonics for inspection and characterization of aeronautic materials

摘要

Aeronautics, because of the requirement of very high safety makes extensive use of nondestructive techniques to verify that the materials and parts used are free of critical flaws. The presence of large areas to be inspected, contoured shapes, the introduction of advanced materials and the aging of current aircraft require further development of these techniques and innovative solutions. Among those, laser-ultrasonics that uses lasers for the generation and detection of ultrasound at a distance presents several advantages for the inspection of aeronautic parts and materials.
