Ultra sensitive detection of radio waves with lasers

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 have developed a new method where they can avoid noise by means of laser light and can therefore achieve extreme precision of measurements.
