Paper Abstract

The method and experimental results of circularity measurements by optical triangulation are presented. The measuring system is a laser based one, using a bi-cell detector with rectangular active surface shape and diagonal gap. The measured data were fitted with a parametric function depending on the position of the tested object center, relative to the center of the rotating table. A resolution of 2.5 micrometers /mW is reported. This sensitivity is satisfactory for the majority of industrial applications-- circularity measurement and centering.
