Abstract :
Steel cleanliness is very important prior to any steel coating process. A novel online cleanliness sensor for steel flat products has been designed. Sensor is based in the optical reflectivity of the dirty steel, which has been analyzed to determine how the incident light beam is dispersed. Lamination/processing steel marks effect on the light dispersion was quantified to be able to design the optical circuit. Fresnel lenses were employed to concentrate the dispersed beam again on a photodiode.
