Abstract
We experimentally demonstrate a three-dimensional x-ray ptychography in combination with precession measurements that can reconstruct multisection images of optically thick objects. We collect a tilt-series ptychographic diffraction data set of a four-layered object and then successfully reconstruct the phase images of each layer by using an improved phase retrieval algorithm with a multislice approach. The present method has great potential for nondestructively determining anisotropic structures in materials science and biology.
