The aim of this study is to gain basic information about matte coating thickness in the area of 3D optical digitization. Thickness measurement was performed for two matting materials; chalk spray and titanium coating. A 3D optical scanner ATOS III, Triple Scan was used for data capturing and evaluation. The scanner technology is based on active fringe projection and triangulation. Fifteen measurements for chalk material and fifteen for titanium coating were carried out. The measurement conditions included the effects of lighting, operation, imperfections of coating materials deposition, etc. The results show significant differences between chalk and titanium matting materials.
