Some interpretations and analysis concerning the accuracy of the thin wire diameter measurement

Abstract

The principle purpose of this work is to providing some general analysis and interpretation in both theory and techniques concerning high accuracy of the thin metallic wire diameter measurement. The closest estimation of the magnitude requires understanding and analyzing the interaction between light and matter (wire). The wires diameter we re concern is between 30 to 500μm. The work is focus on both science and metrology. To reach this goal the simplicity and accuracy is required especially for an industrial automatic implementation control. The article is organized as follow: the section one consist of analyzing and understanding of theoretical interpretation for laser diffraction by thin metallic wire. The second section contains analysis of the experimental set-ups used for calibration and measurement. The followed section is data analysis to estimate the angular location of the minima. With some conclusions we close to achieve the work.
