Mathias Fink, corecipient of the 2011 CNRS medal of innovation

Mathias Fink, director of the Langevin Institute, invented the time reversal mirror in the 1980s, a device capable of recording acoustic or sound waves before retransmitting them backwards. His special mirrors have since found many applications : sending undersea messages only audible to a sensor placed at a specific point, development of touch screens based on the sound signature of each point on a tablet, a diagnostic device for liver diseases based on another of his finds, multi-wave imaging…

Mathias Fink, directeur de l'Institut Langevin, médaille de l'innovation 2011, près de l'une de ses inventions : l'échographe Aixplorer. C'est le premier échographe ultrarapide qui utilise les principes du retournement temporel et de l'imagerie multi-ondes pour réaliser une image de l'élasticité du corps humain. Il permet de diagnostiquer précocément les tumeurs profondes ou imperceptibles à la palpation. Les applications sont très nombreuses et concernent les organes suivants : sein, foie,…
