The most commonly used method in the calibration of step gauges is the coordinate measuring machine (CMM), equipped with a laser interferometer for the highest accuracy. This paper describes a modi cation to a length-bar measuring machine for the calibration of step gauges to a high accuracy. A system was also developed for interferometric measurements of the atness and parallelism of gauge block faces for use in uncertainty calculations.

“…NMIs have suggested different layout for the DEI. [7][8][9] The designed DEI at NIS uses multi-wavelength to avoid the ambiguity in phase measurement. The setup has less optical components as it combines the Michelson configuration with the reflecting mirrors at the measuring arm.…”

The paper discusses the construction of the double-ended interferometer (DEI) at the National Institute for Standards (NIS) for contactless calibration of gauge blocks. The new measuring procedure avoids any contact to the working faces of the gauge block and maintains their quality from possible damage and scratches caused by repeated wringing during periodic calibration. The resulted uncertainty is reduced due to the absence of the auxiliary platen and the corresponding errors of wringing film and phase change. An optical technique based on polarised light is used to measure the surface roughness of the gauge block that influences the measured length. By using the principle angle of incidence, the polarised light technique can be used as an alternative to the stack method to measure the phase change correction with improved accuracy. The constructed interferometer uses multi-wavelength laser sources in illumination to produce a synthetic wavelength that can be suitable to measure the length of the gauge block of interest. The interferogram is analysed by dedicated software to extract the phase information. Optical setup , alignment, measurement, and uncertainty are presented. The comparable calibration results for some gauge blocks of the new technique and the conventional Köster comparator confirm the reliability of the constructed double-ended interferometer.

“…The presented optical setup for contactless gauge block measurement is based on double-ended interferometry combining a laser and a white-light source and it is presented as an alternative to similar configurations published before [4][5][6][7][8]. The key advantage of the presented optical setup is its contactless measurement of the absolute gauge block length done as a single-step measurement giving complete information of the gauge block length, without any additional gauge block manipulation or any length comparison with a reference dimension.…”

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.
