Paper Abstract

The optical method appropriate for studying of the specific surfaces created by abrasive water jets has been assembled and tested. It is based on shadow visualization of random rough surfaces and it makes possible to obtain the shadowing function from distribution of light and shadows. Evaluation of shadowing functions and spectral analyses of signals obtained from surface were performed. Values of a stochastic distribution of light intensity in shadows were quantified using calibration of the experimentally obtained shadowing functions thus defining height distributions of measured profiles of roughness and/or waviness.
