In crystal analyser-based phase contrast imaging (ABI) the phase shift imparted on a partially coherent X-ray wavefield by a weakly absorbing sample is converted into a measurable variation in intensity by diffraction from a crystal. In this talk I will present two results from my thesis, the first relates to the implementation of quantitative ABI using a rotating anode X-ray source and the second is the reconstruction of the complex Green function associated with Bragg reflection from a laterally homogeneous crystal. I will conclude the talk with some recent work on an analytical solution to the phase retrieval problem in coherent diffractive imaging using slits which results in differential wavefield information being recovered.
