System for contactless gauge blocks measurement
This paper presents a novel principle for contactless gauge block measurement using a combination of low-coherence interferometry and laser interferometry.The experimental setup combines a Dowell interferometer and a Michelson interferometer to ensure a gauge block length determination with direct traceability to the primary length standard.This setup was designed for contactless complex gauge block analysis providing information about gauge block length,gauge block faces surface profile (e.g.,indication of scratches) and by analysis of the interference fringes shape,also about the gauge block edge flatness distortion.The designed setup is supplemented by an automatic handling system designed for a set of 126 gauge blocks (0.5 mm to 100 mm) to allow the automatic contactless calibration of the complex gauge block set without a human operator.
