Abstract
Inverse fringe projection adapts the projected pattern to the part, so that a nominally correct surface returns a regular fringe image and deviations show up directly. That normally means a physical master to derive the pattern from. Andreas Poesch sets out conventional fringe projection, the motivation for going inverse, and then the virtual version: generating the adapted pattern from the CAD model rather than from a measured master, with example images of what virtual inverse fringe projection produces.
