Shaping Coherent X-rays with Binary Optics
Stefano Marchesini, Anne Sakdinawat
Diffractive lenses fabricated by lithographic methods are one of the most popular image forming optics in the x-ray regime. Most commonly, binary diffractive optics, such as Fresne…
Advanced Denoising for X-ray Ptychography
Huibin Chang, Pablo Enfedaque, Jie Zhang +7
The success of ptychographic imaging experiments strongly depends on achieving high signal-to-noise ratio. This is particularly important in nanoscale imaging experiments when diff…
Blind Ptychographic Phase Retrieval via Convergent Alternating Direction Method of Multipliers
Huibin Chang, Pable Enfedaque, Stefano Marchesini
Ptychography has risen as a reference X-ray imaging technique: it achieves resolutions of one billionth of a meter, macroscopic field of view, or the capability to retrieve chemica…
