Abstract

The National Research Council (NRC) together with RD-Tech Aero and Universite Laval have been developing a new nondestructive inspection (NDI) system called Intelligent Visual Evaluation (IVE). IVE is based on a new optical sensor technology called Edge of Light (EOL) developed at NRC (Forsyth, D. S., Marincak, A., Komorowski, J. P., Edge of Light: A New Enhanced Optical NDI Technique, Nondestructive Evaluation Techniques for Aging Infrastructure and Manufacturing, Scottsdale Arizona, SPIE Vol. 2945, December 1996, pp. 178-188). EOL is an optically based imaging method that uses oblique angle lighting and obturators to image surface slope changes on the object under inspection. Any phenomenon that affects surface topography can be studied with EOL. Potential spatial resolution and surface slope change resolution are extremely high, yielding a wide range of potential applications.
