Did you know?
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-scale … See more 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 interest. Its … See more There are many optical configurations for ptychography: mathematically, it requires two invariant functions that move across one another while an interference pattern generated by the See more 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 … See more • Phase retrieval • Computational imaging • Fourier ptychography See more Although the interference patterns used in ptychography can only be measured in intensity, the mathematical constraints provided by the … See more 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 See more Beginnings in crystallography The name "ptychography" was coined by Hegerl and Hoppe in 1970 to describe a solution to the crystallographic phase problem first … See more WebDec 15, 2024 · Reflective Fourier ptychography.

WebJun 16, 2024 · Ptychography is a lensless imaging technique that is capable of reconstructing an object and illumination simultaneously by scanning the object at several positions with respect to a localized illumination beam. It has emerged as a powerful tool with applications ranging from high resolution imaging to optical metrology. WebFeb 18, 2016 · Fourier ptychography (FP) is a recently developed imaging technique that iteratively stitches together a number of variably illuminated low-resolution (LR) images in Fourier space to recover a large field of …
WebAug 5, 2024 · Ptychography is a lensless imaging technology that is validated from hard X-rays to terahertz spectral range. It is most attractive for extreme ultraviolet (EUV) and X-rays as optical elements are expensive and often not available. Typically, the set up involves coherently illuminated object that directs the scattered radiation normally to detector …
