Stepping parameter optimization for near-field ptychography

Le résumé fourni par la source

Ptychography is a coherent diffractive imaging method that allows the quantitative reconstruction of phase and amplitude signal of sample and probe. The final reconstruction quality is influenced by a wide range of interdependent parameters, including photon energy, experimental geometry, diffuser type, and sample stepping. This means that varying one factor necessarily requires re-evaluating all others to maintain the reconstruction quality. To address this complexity, the present work investigates, with simulations and subsequent experimental validation, different stepping patterns and step sizes for various diffusers, energies, geometries and sample types.
