Abstract :
We have developed a new imaging technique that unifies analyser-based and propagation-based X-ray phase-contrast imaging. A novel theoretical approach, utilising the theory of linear shift-invariant systems, was employed to solve the phase-retrieval problem for the case of large Fresnel/Takagi numbers. In October 2003, we performed some preliminary experiments at BL20B2 at SPring-8 to illustrate this new imaging technique.
