One of the sources of errors affecting the uncertainty of measurements of the surface texture is the measurement noise, called dynamic noise, which is a combination of the internal noise of the measuring instrument and the influence of the external environment. The article presents the comparison of measurement noise for instruments using various methods of measuring the surface texture that were used during the implementation of the project No. PBS2/A6/20/2013/NCBiR/24/10/2013 “Research and evaluation of reliability of modern methods of surface topography measurements in micro and nano scale”.
