The RFP projects a fringe pattern onto the part surface and the probe’s camera captures the variation in fringe pattern to build a point cloud of 3D surface data. The data cloud is then evaluated by the 3D metrology software to deliver the inspection results. Non-contact structured light inspection with the RFP delivers clear advantages over traditional tactile probing techniques for freeform surfaces and complex geometry, such as additively manufactured parts, aerospace blades and blisks, automotive cylinder head combustion chambers, and delicate surfaces not suited to tactile measurement.
