Dual Laser Interferometer: Introduction to the Development and Initial Findings of the DLI Approach for Ball Bar Certification

Abstract

A ball bar is only as good as the certification behind it. This talk introduces the Dual Laser Interferometer approach to certifying ball bars, its development and the initial findings – work done by Inora Technologies with the Dimensional Metrology Group at NIST, which is the part that matters for anyone who has to defend the traceability of an artefact.
