Sažetak
The paper deals with the description of contemporary methodology of topography evaluation of surfaces created by the abrasive water jet by using the existing standard and non-standard parameters in combination with an autocorrelation function. The grid projection method was used for measurement of samples prepared from stainless steel AISI 309 by abrasive water jet. The optical signals obtained by means of grid projection method of these surfaces were processed by Fourier transform and the norm autocorrelation function in order to get information about height and longitudinal fluctuations. The obtained results are analysed and interpreted.
