传统的三维(3D)成像方法需要在不同方向或扫描下对样品进行多次测量。当用相干波探测样品时，单个二维(2D)强度测量就足够了，因为它包含了3D样品分布的所有信息。我们展示了一种方法，它允许在超过经典极限的z分辨率下，从单个2D强度测量重建3D样本分布。该方法可用于辐射敏感材料，或在实验设置仅允许一次强度测量的情况下。
Conventional three-dimensional (3D) imaging methods require multiple measurements of the sample in different orientation or scanning. When the sample is probed with coherent waves, a single two-dimensional (2D) intensity measurement is sufficient as it contains all the information of the 3D sample distribution. We show a method that allows reconstruction of 3D sample distribution from a single 2D intensity measurement, at the z resolution exceeding the classical limit. The method can be practical for radiation-sensitive materials, or where the experimental setup allows only one intensity measurement.
