A droite , les microphones utilisés pour imager la source. @Bakhtiyar Orazbayev/EPFL - By combining purpose-built materials and neural networks, researchers at EPFL have shown that sound can be used in high-resolution imagery. Imaging allows us to depict an object through far-field analysis of the lightand sound-waves that it transmits or radiates. The shorter the wave, the higher the image's resolution. However, the level of detail is limited by the size of the wavelength in question - until now.
