This optical microphone can ‘see’ sound with incredible precision

Published by

Researchers from Carnegie Mellon University in Pennsylvania, USA, have developed a camera system that can “see” a sound by filming its vibrations. These vibrations can then be used to reconstruct sound with purity and fidelity, enabling the capture of isolated audio with no interference, and no microphone. Beyond the system’s technical prowess, it opens up a World of potential possibilities. To be able to “see” sound, the scientists have developed a camera system capable of capturing the slightest sound vibration with high precision. Composed of two cameras and a laser, the imaging device allo…
