Examples include freeform optics, medical components, large aerospace structures and parts made using additive manufacturing. The measurement of complex form using optical techniques was pioneered over thirty years ago with techniques such as holography and speckle interferometry.
But, the most prominent methods now used in industry are fringe projection and laser triangulation. Both techniques have seen huge commercial success and have spawned thousands of publications.
