Abstract

This paper describes a method for 'stitching' multiple overlapping interferometric measurements of the equator of a high quality sphere to produce a single profile representing the roundness of the ball. The resulting optical profile measurement is compared with one obtained using a mechanical measurement and it is demonstrated that very good agreement exists between the two independent measurements.
