Fresnel Coherent Diffractive Imaging

Abstract: We present an x-ray coherent diffractive imaging experiment utilizing a nonplanar incident wave and demonstrate success by reconstructing a nonperiodic gold sample at 24 nm resolution. Favorable effects of the curved beam illumination are identified.

“…In keyhole coherent diffractive imaging (KCDI), a beam is focused and the object is placed downstream of the focal point so that it is illuminated by a diverging wave 9 . Thus, although the measurement takes place in the far field, the diffracted wave is related to the object via the Fresnel diffraction formalism so that, for an ESW of finite extent, a unique solution for the phase of the diffraction pattern is guaranteed 10 .…”

“…Due to the ltering of the coupled X-rays by propagation through the waveguide [91,222], the prepared quasi X-ray point source is ideally suited for X-ray imaging in the holographic regime [89,165]. In addition, the waveguide source can also be used for iterative phase retrieval of isolated biological specimens in two and three dimensions [12 14] by taking advantage of robust phase retrieval in the Fresnel regime [94,241,334,335]. Moreover, imaging of biological specimens such as bacteria that are prone to radiation damage during the measurement process in this regime is considered to be rather dose e cient [13,14,241].…”
