Abstract

Metal rolls surface laser testing and PC controlled bad rolls detection system is based on optical comparator for two laser beams normally incident on rotating roll surface. Its operation is in two scattered beams intensities variations consequently to changes in defect passing between beams for certain time duration or simultaneous changes due to random roll vibrations. PC signal filtering and data array statistical treatment allows to get scattering coefficients dispersion histograms with lower maximum and greater dispersion halfwidth for bad rolls.
