Crossed-grating phase-shifting profilometry (CGPSP) has great utility in three-dimensional shape measurement due to its ability to acquire horizontal and vertical phase maps in a single measurement. However. CGPSP is extremely sensitive to the non-linearity effect of a digital fringe projection system. which is not studied in depth yet. https://niiejdef9z4n3j.tokka-blog.com/35182210/validation-of-journal-impact-metrics-of-web-of-science-and-scopus
