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.
The approach could help advance real-time remote sensing for military and other applications. For example, it could be used to track vehicles or aircraft traveling through fog. It could also be useful for areas of biomedical research that involve fast-moving particles that cannot be observed directly, according to the researchers.
