Theo Murphy meeting organised by Professor John Rodenburg FRS, Professor Ian Robinson and Dr Andrew Maiden. Ptychography is a form of computational imaging that has distinct advantages over conventional microscopic imaging methods. This meeting will bring together researchers from the X-ray community, who have been using ptychography for about 15 years, with more recent adopters of the technique from the visible light, EUV and electron microscopy communities, as well as theoreticians studying novel applications and algorithms relating to the technique.
