Abstract

The Edge of Lighttrade is a patented technique of the Institute for Aerospace Research, National Research Council Canada. One application of interest is the inspection of aircraft lap joints for pillowing deformation caused by hidden corrosion. This rapid enhanced visual inspection technique provides an intuitive result, which is a representation of surface topography. In this study, the quantification of the surface deformation is investigated by using a laser displacement sensor as a calibration tool. A procedure that implements the reconstruction of 3D surface from Edge of Light scanning is proposed. Experimental results obtained from a bump simulator are presented
