Résumé :

Presents an analysis of the moire fringe self images of two gratings of slightly different spatial periods. The illuminating field is spatially partially coherent and homogeneous. The existence is shown of critical coherence field structures which reduce the visibility of the fringes when self imaging conditions are satisfied.
