除了幅度信息外，还可以从广义衍射实验中获得位相信息(尽管探测器不能直接观察到位相)，但条件是可以以规定的方式控制初级光线。除了在实空间中对称中心的情况外，单个衍射图足以确定相位，并且至少两个衍射图的组合消除了这种模糊性。
In addition to the amplitude information, phase information can also be obtained from a generalized diffraction experiment (in spite of the inability of the detector to observe phases directly) on condition that the primary ray can be controlled in a defined way. A single diffraction pattern suffices for the determination of the phases except in the case of a centre of symmetry in real space, and the combination of at least two patterns removes this ambiguity.
