Recent progress in x-ray Fourier-transform ghost imaging

X-ray diffractive microscopy is a powerful tool in exploring the inner structures of non-crystalline complex samples. However, highly coherent x-ray sources are essential in traditional x-ray diffractive microscopy. Fourier-transform ghost imaging provides the feasibility of achieving high-resolution diffractive imaging with spatially incoherent sources. By taking advantage of the non-local modulation characteristic of ghost imaging, coded Fourier-transform patterns of a sample can be obtained at the Fresnel region and better phase retrieval can be achieved. Here we present our progress on a tabletop x-ray diffractive microscopy system based on Fourier-transform ghost imaging.
