SURFACE TOPOGRAPHY REPRESENTATION IN PROFILOMETRY

• Abstract:

  In the paper the authors presented a comparison analysis of three different probes used for surface topography measurement. Skid and skidless stylus probes were used as contact pick-ups, while an optical autofocussing pick-up was applied as a non-contact one. The analysis was performed using several different topography parameters. It showed that a skid causes some relatively small distortions as far as the surface representation is concerned. The optical probe on the other hand proved to be a very difficult measuring tool, particularly for surfaces with steep slopes and sharp edges. Yet even for very smooth surfaces a great attention must be paid while measuring with this kind of pick-up is considered.
