Ptychography – High resolution microscopy using mathematics instead of lenses

By Eileen De Guire / March 17, 2012

Ptychography is a new approach to microscopy that eschews lenses. Instead, diffraction patterns are collected and reconstructed using algorithms that work backwards to create the image. In this example, the image on the left is a visible light diffraction pattern of a lily anther. The raw data is reconstructed into the image on the right.…
