摘要：
In this paper we present results from simulations on grating-based phase contrast imaging. Herein, the performance of a grating-based interferometer concerning the X-ray's energy is shown. Additionally, geometric parameters of the interferometer were investigated. In the experimental part of this work we present the dependency of the Talbot-Lau interferometer setup on the lower energy threshold of the Medipix-detector. These are the first energy sensitive measurements; acquired within the applied method. Furthermore, we demonstrate the difference between a differential and an integral measurement by comparing the phase and absorption image. The conclusion of this work is the detailed characterisation of grating-based phase contrast imaging regarding its energy dependent behaviour and geometric parameters of the gratings.
