    "abstract": "Interference fringes of total atomic density with period $\\lambda /4$ and\n$\\lambda /2$ for optical wavelength $\\lambda$, have been produced in de Broglie\natom interferometer and directly imaged by means of an ``optical mask\u0027\u0027\ntechnique. The imaging technique allowed us to observe sub-wavelength periodic\npatterns with a resolution of $\\lambda /16$. The quantum dynamics near the\ninterference times as a function of the recoil phase and pulse areas has been\ninvestigated.",
