Web17 Sep 2024 · Fringe projection (FP) [ 7, 8, 9, 10, 11] is a technique based on the Moiré effect which measures 3D shape, from which out-of-plane displacements can be extracted. It takes advantage of a fringe pattern (usually black and white) obliquely projected over the specimen whose image is recorded with a single camera.
