我们比较了X射线荧光全息术（XFH）和多能X射线全息术（MEXH），这两种技术最近被用来获得实验三维原子图像。对于单能全息图，这些方法是等效的凭借光学互易定理。然而，XFH只能在发射物质的特征荧光能量下记录全息信息，而MEXH可以在发射体的荧光边缘以上的任何能量下记录全息信息，从而能够抑制原子图像中的实孪晶重叠和其他像差和伪影。{版权} {美国物理学会}
We compare x-ray fluorescence holography (XFH) and multiple-energy x-ray holography (MEXH), two techniques that have recently been used to obtain experimental three-dimensional atomic images. For single-energy holograms, these methods are equivalent by virtue of the optical reciprocity theorem. However, XFH can only record holographic information at the characteristic fluorescence energies of the emitting species, while MEXH can record holographic information at any energy above the fluorescent edge of the emitter, thus enabling the suppression of real-twin overlaps and other aberrations and artifacts in atomic images. {copyright} {ital 1997} {ital The American Physical Society}
