Fiber optic cable, the thickness of a human hair, can transmit accurate 3D images in
Miles Padgett of the University of Glasgow(UK) and his colleagues have developed a system that is several orders of magnitude smaller than existing fiber-optic cameras. The system uses a cable 40 centimeters long and 50 micrometers in diameter. It can take 3D images of objects up to 2.5 meters away.

Early researchers used a similar approach and introduced a new microscopy technique that allows the visualization of animal tissue. It will help to study biological phenomena in even more detail.
The new approach is extended microscopy,based on the method of suppression of spontaneous emission (STED) - a breakthrough technique that allows you to achieve nanoscale resolution by overcoming the diffraction limit of optical microscopes. For developing this technique, Stefan Hell received the Nobel Prize in Chemistry in 2014.
