Measuring and modelling Surface Appearance for the surface topography control – NAPS
The measurement and modelling of surface visual appearance is a challenge and an important issue at both scientific level and in their industrial applications, as quality inspection, and controlling the surface manufacturing and finishing processes :
(i) how to measure visual appearance indicators, how to qualify a surface appearance from objective and robust indicators
(ii) how to determine functional correlations between the surface appearance and the surface micro-geometry
The NAPS project propose to answer these two issues, at both hardware and methodology levels, by the design of an innovative device to measure surface appearance (restricted to the angular and spectral component of the reflectance), and by the implementation of methods that allow to reconstruct the angular reflectance efficiently. The proposed methods also aim to make easier the determination of functional correlations between the surface appearance and its geometry.
