Surface Topography Filtering

  • P. J. Sullivan


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:
  1. 1.

    mechanical — e.g. a skid, stylus radius, traverse length;

  2. 2.

    electrical — sampling rate, 2RC, CCD pixel transfer function;

  3. 3.

    digital — convolution filtering.
