论文摘要
常规的三维(3D)成像方法需要在不同的方向或扫描中对样品进行多次测量。当样品用相干波探测时,单个二维(2D)强度测量就足够了,因为它包含3D样本分布的所有信息。我们显示了一种方法,该方法允许从单个2D强度测量值重建3D样本分布,以超过经典限制的Z分辨率。该方法对于辐射敏感的材料可能是实用的,或者实验设置仅允许一个强度测量。
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.
