Paper Abstract

The characterization of surface microtopography by Nomarski Differential Interference Microscopy, using digital image processing, is compared with measurements obtained from contact profilometry. The limitations of the two techniques for characterizing rolled-metal surfaces are discussed. The advantages of using the distribution of surface slopes for evaluating surface quality in rolled aluminum sheet is highlighted.
