Optics and photonics. Interferometric measurement of optical elements and optical systems - Terms, definitions and fundamental relationships Ingestion-build-63436 procurement and construction methods that1 Scope This part of ISO TR 14999 gives terms, definitions and fundamental physical and technical relationships for interferometric measurements of optical wavefronts and surface form of optical elements. It explains why some principles of the construction and use of interferometers are important due to the wave nature of the wavefronts to be measured. Since all wavefronts with the exception of very extended plane waves do alter their shape when
