Revolutionary Magnetometer Technology Developed by Raman Research Institute

A quantum leap in magnetometry could simplify magnetic field measurements. Researchers have developed a new technology that could help measure the invisible forces of magnetism without needing bulky shielding or ultra-quiet labs. Magnetometers are useful devices with applications in areas ranging from fundamental physics to medical imaging and navigation. The most promising methods for magnetic field measurement are based on detecting polarization rotation of a probe light passing through alkali atoms in a very weak magnetic field. Researchers at the Raman Research Institute (RRI) have devised a novel method for magnetometry in an all-optical quantum magnetometer that could transform the way we measure magnetic fields—making the process faster, portable and precise even in noisy, real-world environments.

RDSNS uses laser light to listen to the tiny quantum jitters of Rubidium atoms. By shining lasers and analyzing the noise, researchers can accurately measure the magnetic field without touching or disturbing the atoms. Their setup works without magnetic shielding, making it suitable for outdoor, industrial, and clinical environments. The device achieved high sensitivity and dynamic range while being compact and immune to interference.

The method could revolutionize brain and nervous system scanning, mineral prospecting, and space exploration. The research article was published in the journal IEEE Transactions on Instrumentation and Measurement through an initiative under the National Quantum Mission of DST.
