Ptychography can be used with visible light, X-rays, extreme ultraviolet (EUV) or electrons. Unlike conventional lens imaging, ptychography is unaffected by lens-induced aberrations or diffraction effects caused by limited numerical aperture [citation needed]. This is particularly important for atomic … Zobraziť viac Ptychography (/t(ʌ)ɪˈkogræfi/ t(a)i-KO-graf-ee ) is a computational method of microscopic imaging. It generates images by processing many coherent interference patterns that have been scattered from an object of … Zobraziť viac There are many optical configurations for ptychography: mathematically, it requires two invariant functions that move across one another … Zobraziť viac Applications of ptychography are diverse because it can be used with any type of radiation that can be prepared as a quasi-monochromatic propagating wave. Ptychographic imaging, along with advances in detectors and computing, has resulted in the … Zobraziť viac • Phase retrieval • Computational imaging • Fourier ptychography Zobraziť viac Although the interference patterns used in ptychography can only be measured in intensity, the mathematical constraints provided by the translational invariance of the two functions (illumination and object), together with the known shifts between them, means … Zobraziť viac Lens insensitive Ptychography can be undertaken without using any lenses at all, although most implementations use a lens of some type, if only to condense radiation onto the specimen. The detector can measure high angles of Zobraziť viac Beginnings in crystallography The name "ptychography" was coined by Hegerl and Hoppe in 1970 to describe a solution to the crystallographic phase problem first … Zobraziť viac Web7. apr 2024 · In this work, we explore reconstructions with undersampled data for meter-scale reflective based Fourier ptychographic imaging.
