A new method for building an atomic matter-wave interferometry is proposed. In this paper, a Fresnel zone-plate is used for restricting the linewidth of atomic beams, then a quasi-monochromatic atomic beam is obtained to illuminate four slits on a copper coil. The phenomenon of atomic interference and holograph can be observed, which is used to measure the coherent length of atomic beams.
