The neutron interference imaging technique has been developed for these years with several methods. Here we introduce recent results of neutron interference method. The neutron interference imaging experiment with two absorption gratings has been done. We develop new way to fabricate absorption gratings for neutron with the pitch of 150 μm, 180 μm, and 200 μm. Small break in an acrylic plate was observed. We expect that the neutron interference imaging method can become new method of a nondestructive inspection method for reinforced plastics and composite material such as CFRP and so on especially installed at compact neutron source which is being developed in RIKEN now.
