Abstract: The contribution deals with the analysis of the optical data obtained from the surfaces generated by hydroabrasive dividing of materials. The samples of different materials were prepared at the Academy of Sciences of the Czech Republic. The comparison of further results performed between the commercial contact profilometer HOMMEL TESTER T8000 and the contactless shadow method developed included its calibration. On the basis of the optical data analysis, the results evaluated especially the height irregularities of the surface topography caused by hydroabrasive cutting planes. The evaluation of the surface topography generated by abrasive waterjet was realised via spectral analysis. The amplitude-frequency analysis of the signals generated on surface topography was mainly realised.
