3-D imaging based on hard x-ray grating interferometry: theory, development and application

This thesis focuses on the development and optimization of Talbot grating interferometry for phase contrast imaging of laterally extended samples with high speed. This development is established by a theoretical description of the forward problem of image formation and the inverse problem of data retrieval, supported by numerical calculations and confirmed in exemplary experiments. The potential of two new developed instruments is demonstrated by a wide variety of imaging applications.
