The NPL guide describes good practice for the measurement and characterisation of rough surface topography using coherence scanning interferometry (otherwise known as vertical scanning white light interferometry). It is aimed at users of coherence scanning interferometry for the optical measurement of surface texture within production and research environments.
The British Standards Institution (BSI) has also published a guide on the measurement and characterisation of surface topography whose principal author was NPL's Prof Richard Leach. This guide is available to purchase online at BSI.
This project is funded by the National Measurement System (NMS), the UK's national infrastructure for measurement.
