    en.wikipedia.org/wiki/Metrology

    Metrology is a wide reaching field, but can be summarized through three basic activities: the definition of internationally accepted units of measurement, the realisation of these units of measurement in practice, and the application of chains of traceability (linking measurements to reference standards).

  6. Coordinate-measuring machine - Wikipedia

    en.wikipedia.org/wiki/Coordinate-measuring_machine

    A coordinate-measuring machine (CMM) is a device that measures the geometry of physical objects by sensing discrete points on the surface of the object with a probe. Various types of probes are used in CMMs, the most common being mechanical and laser sensors, though optical and white light sensors do exist.
