Researchers at the University of Southampton and Nanyang Technological University have developed a non-invasive approach for optical measurements with atomic-scale resolution using topologically structured light and deep learning. Their proof-of-principle experiments resolved the position of a suspended nanowire with a subatomic precision of 92 pm, thousands of times better than conventional microscopes. This approach could open up new possibilities for research in a variety of fields, allowing scientists to characterize systems or phenomena at the scale of a fraction of a billionth of a meter.
