The aircraft lap joints are inspected with an enhanced visual inspection technique named 'Edge of Light', which is patented by the NRC Institute for Aerospace Research. This technique is applicable for rapid detection of possible hidden corrosion in lap joints. The surface deformation due to hidden corrosion can be characterized by this optical-based inspection method. In this study, a calibration procedure is developed to quantify the lap joint surface deformation. The effect of surface reflectivity is investigated with the solid film highlighting technique (SolidHi), which helps achieve a uniform reflectivity during the inspection. The efficiency of the technique is demonstrated with the experimental results.
