Phase retrieval based on a total‐variation‐regularized Poisson model for X‐ray ptychographic imaging of low‐contrast objects

Hard X‐ray ptychography has become an indispensable tool for observing the microscopic structure of a thick specimen. It measures diffraction patterns by scanning an X‐ray beam and visualizes the complex‐valued refractive index of the specimen by a computational reconstruction called phase retrieval...
