Coherent diffractive imaging and partial coherence
نویسندگان
چکیده
We formulate coherent diffractive imaging in the framework of partially spatially coherent diffraction. We find that the reconstruction can be critically dependent on the degree of coherence in the illuminating field and that even a small departure from full coherence may invalidate the conventional assumption that a mapping exists between an exit surface wave of finite support and a far field diffraction pattern. We demonstrate that the introduction of sufficient phase curvature in the illumination can overcome the adverse effects of partial coherence.

High-resolution three-dimensional partially coherent diffraction imaging.
The wave properties of light, particularly its coherence, are responsible for interference effects, which can be exploited in powerful imaging applications. Coherent diffractive imaging relies heavily on coherence and has recently experienced rapid growth. Coherent diffractive imaging recovers an object from its diffraction pattern by computational phasing with the potential of wavelength-limit...
متن کاملDiffractive imaging using partially coherent x rays.
The measured spatial coherence characteristics of the illumination used in a diffractive imaging experiment are incorporated in an algorithm that reconstructs the complex transmission function of an object from experimental x-ray diffraction data using 1.4 keV x rays. Conventional coherent diffractive imaging, which assumes full spatial coherence, is a limiting case of our approach. Even in cas...
متن کاملLensless imaging using broadband X-ray sources
High-resolution X-ray imaging techniques using optical elements such as zone plates are widely used for viewing the internal structure of samples in exquisite detail. The resolution attainable is ultimately limited by the manufacturing tolerances for the optics. Combining ideas from crystallography and holography, this limit may be surpassed by the method of coherent diffractive imaging (CDI)1....
متن کاملStatistical optics and optical elements for microtechnologies: Partial coherence, lithography and microlenses
The scientific problems treated in this thesis are expressed within the framework of statistical optics and are generated out of the optical lithography industry. Optical lithography uses partially coherent light, i.e. light with a random wavefront, to increase the performance of the lithographic process. One of the goals of this work has been to explore ways to numerically simulate the behavio...
متن کاملCurved beam coherent diffractive imaging
We discuss a coherent diffractive imaging experiment wherein the illuminating X-ray beam is divergent, rather than planar. By reconstructing the illumination at the sample, it is possible to recover the exit surface wave in that plane. With this geometry, the usual iterative reconstruction scheme converges very quickly, without finding the typical ambiguous solutions. © 2007 Elsevier B.V. All r...
