SEEING
THROUGH WALLS: Laser System Reconstructs objects hidden from sight
By
combining bouncing photons, the particles of light, with advanced optics,
researchers are able to ‘see’ 3-D images of objects hidden around a corner
WASHINGTON,
Aug. 6, 2012 – Inspired by the erratic behavior of photons zooming around and
bouncing off objects and walls inside a room, researchers from the Massachusetts
Institute of Technology (MIT), Harvard University, the University of Wisconsin,
and Rice University combined these bouncing photons with advanced optics to
enable them to “see” what’s hidden around the corner. This technique, described
in a paper published today in the Optical Society’s (OSA) open-access journal
Optics Express, may one day prove invaluable in disaster recovery situations,
as well as in noninvasive biomedical imaging applications.
