The field of Large-Scale Metrology has been studied extensively for many decades and represents the combination and competition of topics as diverse as geodesy and laboratory calibration. A primary reason that Large-Scale Metrology continues to repre

Interferometric radius measurements may be completed using a radius bench, where radius is defined as the displacement between the confocal and cat's eye nulls (identified using a figure measuring interferometer). Measurements of a Zerodur sphere hav

We present a new technique for calibrating the apex angles of dispersion prisms, which are used in the measurement of the index of refraction of optical glasses. The new method requires only a phase measuring interferometer, together with an electron

We describe the use of Bayesian inference to include prior information about the value of the measurand in the calculation of measurement uncertainty. Typical examples show this can, in effect, reduce the expanded uncertainty by up to 85 %. The appli

We analyze two types of full-circle angle calibrations: a simple closure in which a single set of unknown angular segments is sequentially compared with an unknown reference angle, and a dual closure in which two divided circles are simultaneously ca

This paper examines the measurement uncertainty of small circular features as a function of the sampling strategy; i.e., the number and distribution of measurement points. Specifically, we examine measuring a circular feature using a three-point samp
