Abstract
Fringe projection combines the advantages of triangulation with those of real-time interferometry: graycode and phase-shift sequences projected in turn, DLP giving high contrast and strong light, and two cameras assessing the projected patterns to build a 3D image of the surface. This talk takes the technique from introduction through to a working coordinate measuring capability, covering the calibration and achievable accuracy of the method and then two demanding subjects – a cutting insert, where the edges are the point, and gearwheels, where the flank geometry is.
