Description
Single-shot coherent diffractive imaging with intense XUV and soft X-ray pulses offers the exciting possibility of retrieving both the 3D structure and optical properties of nanoscale objects from a single diffraction pattern. Achieving this, however, requires an accurate description of the underlying wide-angle scattering and propagation effects, which are significantly more complex than in conventional X-ray diffraction.
I will introduce the propagation multi-slice Fourier transform method (pMSFT) [1], a fast and accurate approach for simulating the scattering process in this regime. Its derivation from first principles will be outlined, a unified physical picture to show its relation to existing methods is introduced, and finally systematic benchmarks demonstrating its superior performance for wide-angle scattering are presented.
