Laser-crystal sensor measures strong magnetic fields in challenging environments
Researchers at Sandia National Laboratories have patented a magneto-optical sensor, which uses a rare earth crystal and laser light to measure the strength of intense magnetic fields and electrical currents.
“We think this technology is a pretty major improvement in measuring magnetic fields,” said Israel Owens, a Sandia physicist and co-inventor of the sensor. “We think it’ll be essential especially for research in fusion, high-energy physics, and the power utilities industry. We’re really excited about where things are going.”
