In this article we describe a novel optical sensor designed to measure surface texture, i.e., the roughness and waviness. The system integrates a surface profiler and a light scattering unit in a compact setup suitable for industrial applications. This sensor could represent a unique surface inspection tool to be integrated in grinding stations used for reconditioning rolls for milling. The spatial wavelength measuring range for waviness is 1-100 mm, whereas the amplitudes of the measured defects can be in the range 200 nm-5 μm for waviness and 100 nm-1.5 μm for roughness. The system exhibits a measurement uncertainty of less than 2% of the measuring range. The industrial version of the sensor has been realized and characterized in field.

Abstract

In this article we describe a novel optical sensor designed to measure surface texture, i.e., the roughness and waviness. The system integrates a surface profiler and a light scattering unit in a compact setup suitable for industrial applications. This sensor could represent a unique surface inspection tool to be integrated in grinding stations used for reconditioning rolls for milling. The spatial wavelength measuring range for waviness is 1-100 mm, whereas the amplitudes of the measured defects can be in the range 200 nm-5 μm for waviness and 100 nm-1.5 μm for roughness. The system exhibits a measurement uncertainty of less than 2% of the measuring range. The industrial version of the sensor has been realized and characterized in field.
