Abstract：
Neutron penumbral imaging technique is an important diagnosis method in Inertial Confined Fusion, and the design of the aperture shape will affect the resolution of the imaging system. In this paper, several designs of the aperture shape are discussed. Moreover, the pointing precision is also discussed, and a rational pointing precision is given.
