(April 23, 2015) Thermal
imaging, microscopy and ultra-trace sensing could take a quantum leap with a
technique developed by researchers at the Department of Energy’s Oak Ridge
National Laboratory.
“Quite simply, under certain circumstances, our method
enables us to see things we couldn’t see before,” said Raphael Pooser,
co-author of a paper published in the journal Optica. He and Benjamin Lawrie
used quantum correlated beams of light to overcome the fundamental detection
limit of microcantilever-based sensors caused by intensity fluctuations.
