Ptychography - Wikipedia
https://en.wikipedia.org/wiki/Ptychography
WebPtychography (/t(ʌ)ɪˈkogræfi/ t(a)i-KO-graf-ee) [citation needed] 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.
