Abstract

The characterization of a surface, especially the roughness, is of great importance for industrial applications. There are already various optical methods for roughness measurement, which usually do not consider the depolarization effects of the scattered beam caused by the sample. This work aims out improving the roughness measurement method described in [1] by taking into account depolarization effects, due to the rough sample. For validation, other instruments are employed to compare the results in the measurement interval for which this technique is applied.
