摘要翻译：
相位恢复是相干衍射成像(CDI)等多种成像应用的基础。典型的相位恢复算法在本质上是迭代的，因此，耗时和计算昂贵，排除了实时成像。此外，迭代相位恢复算法很难收敛到正确的解，尤其是在强相位结构存在的情况下。在本工作中，我们演示了CDI神经网络的训练和测试。CDI神经网络是一对深度反卷积网络，它被训练用来仅根据二维物体的远场衍射强度来预测其在真实空间中的结构和相位。一旦经过训练，CDI神经网络可以在标准台式计算机上几毫秒的计算时间内将衍射图案转换成图像，为实时成像打开了大门。

英文摘要：
  Phase retrieval, or the process of recovering phase information in reciprocal space to reconstruct images from measured intensity alone, is the underlying basis to a variety of imaging applications including coherent diffraction imaging (CDI). Typical phase retrieval algorithms are iterative in nature, and hence, are time-consuming and computationally expensive, precluding real-time imaging. Furthermore, iterative phase retrieval algorithms struggle to converge to the correct solution especially in the presence of strong phase structures. In this work, we demonstrate the training and testing of CDI NN, a pair of deep deconvolutional networks trained to predict structure and phase in real space of a 2D object from its corresponding far-field diffraction intensities alone. Once trained, CDI NN can invert a diffraction pattern to an image within a few milliseconds of compute time on a standard desktop machine, opening the door to real-time imaging.
