An interesting spacial moire hologram and its reconstruction were recommended. Some properties of reconstruction moire and its prospect of application were also discussed. A spacial moire hologram is given in this paper. The object of the hologram is two groups of transparant and opaque per or quasi-periodical grating, grid, Fresnal zone plate and so on. In order to form different kinds of spacial moire patterns, a certain spacing between two gratings is needed. Besides, they would be parallel, tilted or twist to form different structures of spacial moire. When reconstruction of the hologram, in the modulated optical field, there are not only the original per or quasi-periodical structure, but also the spacial bit frequency pattern --- the spacial moire fringe can be obtained.
