The title of the talk is ‘Sensor Technologies for Inspection and Monitoring’. Various applications in the manufacturing context involving the combination of sensor technologies and artificial intelligence will be discussed in relation to inspection and monitoring. Specifically, the applications that will be discussed in the talk include inspection of armour ceramics used in personal protection, detecting delamination in multilayered composite structures used in aerospace components, identifying defects in enamelled copper wire on line and in real time anddetecting porosity in aluminum castings. A new inspection technology, Laser Ultrasonics will also be discussed. The main sensing method to be discussed in the talk will be high frequency ultrasound and the primary artificial intelligence tool used in these applications is artificial neural networks. The sensor signals obtained in industrial environments are generally ‘noisy’ and the use of wavelet transforms to filter out ‘noise’ will also be briefly discussed. Feature selection is also an important element in the effective use of neural networks and other artificial intelligence tools, and this topic will also be discussed in the context of the application involving inspection of armour ceramics.
