With conventional microscopy, if a scientist wishes to obtain a high-resolution image of a relatively broad area, they typically have to use a microscope that scans across that area in a grid pattern, recording many images one point at a time. Those images are then joined together to form one complete picture. Such systems take a long time to perform a scan, so both the microscope and the subject must be held still while it's taking place. Researchers from Germany's Fraunhofer Institute for Applied Optics and Precision Engineering, however, have created a thin, handheld microscope that can reportedly obtain similar-quality images in less than one second.
