Abstract: A Ski base Structure Analyser (SSA) utilising laser technology has been developed to analyse the detailed structure of a stone-ground ski base. The SSA displays the measured surface as an image with 739 x 570 pixels, where each pixel can have a grey level value from 0 to 255. The value of each pixel is proportional to the height at the corresponding point of the measured surface. Various roughness parameters can be calculated from the measured surface image in order to characterise the surface topography. Some of these parameters are described in this paper. Further the paper contains examples of calculated SSA parameters from a typically measured surface image using MATLAB.
