Instrumentation measurement testing. Researchers testing high-precision measuring instruments by the use of standards artefacts (centre) of known properties. These devices are 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 | |
