Abstract

The usual moire method consists in projecting a grid, that is made of parallel straight lines, onto an object. Then a moire picture is obtained, which is made of cured fringes. In the inverse moire method, we compute a specific grid that is made of straight fringes. The object must be known, but small deformations from a known mean shape can be analyzed with very simple fringe processing. We show some examples of reconstruction by inverse moire.
