从单个2D衍射测量进行3D重建的可行性
Feasibility of 3D reconstructions from a single 2D diffraction measurement
摘要：
我们对Raines等人[arXiv：0905.0269v2]（现发表于Nature，第463卷，第214-217页，2010年）的最新手稿进行了评论，该手稿表明，在某些条件下，单次衍射测量可能足以重建散射体的完整三维密度。我们表明，过去的文献包含的工具，严格评估这种方法的可行性。我们的问题的重建算法的制定所使用的作者，我们认为，作为示范的实验数据是不适合这种方法，因此，重建是无效的。第二个版本是为了文件目的而制作的。除了经过最低限度修改的原始评论外，它还在附录中包括随后对作者之一（J. Miao）的答复。
英文摘要：
We comment on the recent manuscript by Raines et al. [arXiv:0905.0269v2] (now published in Nature, vol. 463, p. 214-217, 2010), which suggests that in certain conditions a single diffraction measurement may be sufficient to reconstruct the full three-dimensional density of a scatterer. We show that past literature contains the tools to assess rigorously the feasibility of this approach. We question the formulation of the reconstruction algorithm used by the authors and we argue that the experimental data used as a demonstration is not suitable for this method, and thus that the reconstruction is not valid. This second version was produced for documentation purposes. In addition to the minimally modified original comment, it includes in appendix a subsequent reply to one of the authors (J. Miao).
