Paper Abstract

Several simple models based on the geometrical theory of diffraction have been developed to be used in automatic control diameter of wires by optical diffraction, within the range of 10–200 µm. The experimental diffraction patterns are analyzed by Kriging method in order to estimate with good accuracy the location and the uncertainty of each minimum. The best geometrical model is selected by statistical analysis taking into account the uncertainty of the minima. The chosen model is used for the automatic determination of the wire diameter in systems of inspection and control.
