通过使用叠层成像技术，物体的相干衍射成像变得更加实用，其中一组衍射图案取代了单个测量，并在记录的数据中引入了高度的冗余。在这里，我们证明这种冗余允许将衍射图案外推到记录设备孔径之外，从而产生超分辨率图像，将最精细特征分离的限制提高了 3 倍以上。 (C) 2011 年美国光学学会
Coherent diffractive imaging of objects is made considerably more practicable by using ptychography, where a set of diffraction patterns replaces a single measurement and introduces a high degree of redundancy into the recorded data. Here we demonstrate that this redundancy allows diffraction patterns to be extrapolated beyond the aperture of the recording device, leading to superresolved images, improving the limit on the finest feature separation by more than a factor of 3.
