Project: Angle metrology

Many areas of science and industry rely on the accurate measurement of angles. From the precision form measurement of optical surfaces, used at synchrotron radiation beamlines and free electron laser (FEL) centres, to the precision engineering measurements of flatness, straightness and parallelism, used by the automotive and aerospace industries to ensure parts are produced to the correct specifications. Increasing demands on manufacturing accuracy are raising the need for improvements in the devices used to make these measurements, and in their calibration. This project will develop prototype devices to realise the radian, the SI unit of angle, to help ensure the reliable and traceable measurement of angles in science and industry. It will also address a wide range of angle measuring devices, such as autocollimators, angle encoders and small angle generators, looking at the applications of these devices and how they perform in challenging measuring conditions.
