Surface Topography Filtering
We have seen from Chapter 3 that measuring a surface implicitly involves filtering the surface. In other words it is impossible to measure a surface without applying a filter to the measurand. Examples of filters encountered in surface topography measurement systems include:
mechanical — e.g. a skid, stylus radius, traverse length;
electrical — sampling rate, 2RC, CCD pixel transfer function;
digital — convolution filtering.
