Ghost Imaging Speeds Up Superresolution Microscopy

Scientists from the Chinese Academy of Sciences have developed a new imaging technique that produces nm-scale resolution using significantly fewer images than traditional nanoscopy techniques. The scientists used ghost imaging to enhance the imaging speed of their technique. The new approach could be useful for live cell imaging. The technique is based on stochastic optical reconstruction microscopy (STORM), a wide-field microscopy method that uses fluorescent labels that switch between light-emitting (on) and dark (off) states. By acquiring hundreds or even thousands of images, each capturing the subset of fluorescent labels that are “on” at a given time, STORM allows the user to determine the location of each molecule...
