Stitching of equatorial profiles for extended spatial range assessment
- Sullivan, P. J.; Parks, R. E.; Shao, L.
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.
