One of the greatest problems in microscopy is resolving two closely spaced objects as separate, with the minimum distance previously thought to be fundamentally-limited by the diffraction of light. However, new research from the National University of Singapore utilizes modern advances in quantum-information theory to extract even more information from detected light. This new optical method – spatial-mode demultiplexing (SPADE) – also utilizes a specialized multichannel detector for separating the detected light by mode, capable of super-resolution.
