Système de détection des rayons cosmiques à partir de téléphones portables en réseau

in Général, Sciences 

The Distributed Electronic Cosmic Ray Observatory (DECO) is an effort to harness the global network of mobile devices (primarily devices running Android software), to detect the origin and behavior of the cosmic radiation

While the cameras found in cellphones are designed to image in the visible portion of the spectrum, they can also detect other phenomena usually disregarded as noise for the purpose of taking pictures. The active element found in the cameras in cell phones is an array of charge-coupled devices (CCDs) which are sensitive to the visible portion of the electromagnetic spectrum. During the course of normal operation a CCD array will absorb photons and generate a small buildup of charge at each pixel corresponding to the intensity of the incoming photon.
