Instrumentation measurement testing. High-precision measuring instruments being tested by the use of a standards artefact (centre) of known properties. This device is designed for use in measurements involving form (shape) and reflectance. The latter relates to properties involving sound waves and electromagnetic radiation. The results are shown on the screen. Photographed in 2015, at the National Physical Laboratory, Teddington, UK.
