CMSC 2019 PRESENTATION - Uncertainty evaluation of fringe projection based on linear systems theory Fringe projection (FP) techniques offer fast, noncontact measurements of the surface form of manufactured parts. FP systems detect the intensity of a projected fringe pattern that is reflected from the surface to be measured. Any process that alters the... Citation: George Gayton University of Nottingham
