• Interference fringes in X-ray diffraction must be a projected figure thrown to thewave-traveling direction, due to the property of the wave field that A K= const. along7-1IIthe wave path and AKLK (AK=K -K and K= -(K-I-K'),K and K' benng the wavevectors of interfering waves in vacuum). The second property comes from the condi-Lion IAI = IK' l. The question of whether moire fringes have this projective propertywas examined experimentally. Moire fringes were observed from a monolithic Sibicrystal by X-ray topography. Experiments have shown that the directions and posi-tions of moire fringes vary with the shift of the observation point along the wave pathin oscillatory manners, and thus the moire fringes are not exactly the projected figure.This fact indicates that the first or both of the conditions, dA=const. and AKI-K,do not apparently hold in the moire-fringe interference.
