Absolute and comparative measurements of three-dimensional shape by phase measuring moiré topography

We describe a phase-measuring version of projection moiré topography which allows fully automatic on-line analysis of moiré fringe contour patterns. The technique can be used for both absolute and comparative measurements of surface form and an example of each type of measurement is presented.
