JRP SIB58 Angles - Angle Metrology project is supported under European Metrology Research Programme (EMRP) and will run between September 2013 and 2016. The project compromising 16 consortium partners from advanced National Metrology Institutes, manufacturers and research organisations in Angle Metrology: TÜBİTAK UME (TURKEY), CEM (Spain), CMI (Czech Republic), INRIM (Italy), IPQ (Portugal), LNE (France), MG (Poland), MIKES (Finland), PTB (Germany), SMD (Belgium), AIST (Japan), FAGOR (Spain), KRISS (Korea), MWO (Germany) and HZB (Germany).
Angle metrology is a key enabling technology for scientific and industrial areas of high value in which the EU is globally competitive. Many application areas exist, including: the precision form measurement of optical surfaces (e.g., beam-shaping optics in synchrotron radiation beamlines and Free Electron Lasers - FEL - and flatness standards for interferometer calibration); precision engineering, (e.g., the measurement of machine geometries – straightness, flatness, and parallelism); industrial applications (e.g., in automobiles, airplanes, and industrial robots), and a range of scientific applications (e.g., the measurement of the gravitational constant G and the angular stabilisation of x-ray optical components). New angle measuring devices have been developed which pose challenges such as the precise characterization and calibration of autocollimators and angular encoders with lower uncertainties and the development of small angle generators with nrad uncertainty is required for ensuring the traceability.
The project will be coordinated by Dr. Tanfer YANDAYAN from TÜBİTAK UME and expected to go beyond the current state of the art by performing investigations, experimental work, and by developing prototype devices for the realisation of the SI angle unit ‘radian’ with an expanded uncertainty less than 0.01” (50 nrad). This work will ensure the reliable and SI traceable measurement of angles in industrial and scientific applications of angle measuring instruments.
