By listening to optical `noise,` researchers discover new way to track hidden objects
(PHYSorg.com Physics)

Researchers have developed a new solution to tracking objects hidden behind scattering media by analyzing the fluctuations in optical `noise` created by their movement. In The Optical Society`s journal for high impact research, Optica, researchers from the University of Central Florida (CREOL) demonstrate their technique by tracking the location of an object as it is moved within an enclosed box.
