Numerical and experimental study of the characteristic functions of polygon scanners

摘要

A MathCad analysis of the mathematical functions and parameters of polygonal scanning heads is achieved. The results of a previous, rigorous analytical study we have performed are used. A scanning system for dimensional measurements has been considered. However, most of the results obtained are valid for any application of polygon mirror (PM) scanners. The characteristic functions and parameters of the PM scanner in the dimensional measurements setup, i.e. i.e. scanning function and velocity, characteristic angles and duty cycle are discussed. The analysis is performed with regard to the constructive parameters of the polygonal scanning system. An experimental stall is designed and constructed, and some of the experimental results concerning the scanning function, relevant for the analysis performed are presented.
