Book excerpt: Advances in Optical Form and Coordinate Metrology covers the latest advances in the development of optical form and coordinate measuring instruments plus the manipulation of point cloud data. The book presents some basic principles of the optical measurement methods and takes a deeper look at the operation of the instruments and the new application areas where they can be applied, with an emphasis on advanced manufacturing. Latest advances discussed include the drive towards faster instruments for in-process applications, the ability to measure highly complex objects (in e.g. additive manufacturing), performance verification and advances in the use of machine learning to enhance data analysis.
