Abstract

Metal inner and outer ring of railway carriages wheels bearing unit surfaces laser testing and PC controlled inspection system is based on laser beam normally incident on rotating ring surface scattered intensity measurement. Its operation is in the surface scattered image recording consequently to changes in surface defect passing through laser beam for certain time duration. PC image processing, filtering and data array statistical treatment allows to get scattering coefficients dispersion histograms and measure the defects square in ring surface.
