Abstract
In fringe-projection and deflectometric measurements that use structured illumination, measurement artefacts can be observed around abrupt changes of surface reflectivity. This can lead to incorrect error classification. We explore the origin of the phenomenon by simulation and modelling, and offer a first attempt at correcting these errors.
