'Reversing the problem' clarifies molecular structure

Optical techniques enable us to examine single molecules, but do we really understand what we are seeing? After all, the fuzziness caused by effects such as light interference makes these images very difficult to interpret. Researchers at the University of Twente’s MESA+ Institute for Nanotechnology adopted a “reverse” approach to spectroscopy which cleaned up images by eliminating background noise. The researchers presented their findings in Physical Review Letters.
