| Abstract: | In this paper a laser triangulation scanning method for the non-contact measurement of scratches on aircraft skins and aircraft window surfaces is described. According to analyses of the diffusing and reflecting properties about the measurcd surface, the correct setting of the laser triangulation probe is given. The adjusting posture of probe method and the spraying surface method have been developed to improve the measuring accuracy. The measurement system is characterized by long working distance, wide measuring range, high measuring accuracy, simple structure as well as low cost. The experimental results are given. |
