| 中文摘要 | x-ray phase imaging with illumination by a partially coherent source with a setup similar to in-line holography is considered. using the optical transform function, we consider the effects of partial coherence on this x-ray phase imaging for a weak phase object. the optimal contrast and the resolution of phase imaging are analyzed. as the coherence decreases, the imaging contrast and the optimal contrast frequency decrease, and the resolution degrades. it is shown that this contrast-enhanced phase-imaging method can be regarded as a linear bandpass filter and that the bandwidth and the image contrast are changeable. the frequency property of the imaging system can be improved if an incoherent x-ray source with the proper shape is used.
