Ultra Sensitive Detection Of Radio Waves Using Lasers
2014-03-05 14:30:33

University of Copenhagen - Niels Bohr Institute Radio waves are used for many measurements and applications, for example, in communication with mobile phones, MRI scans, scientific experiments and cosmic observations. But 'noise' in the detector of the measuring instrument limits how sensitive and precise the measurements can be. Now researchers at the Niels Bohr Institute have developed a new method where they can avoid noise by means of laser light and can therefore achieve extreme...
