The Pentagon has started a project aimed at capturing light wave history that will allow troops to see behind walls.
According to Nextgov, this technology, as mentioned in Defense Advanced Research Projects Agency's (DARPA) announcement, might eventually help troops prepare for hidden threats, assailants hidden behind barriers, for instance.
Predrag Milojkovic, a program manager in DARPA's Defense Sciences Office, said that the research aimed at using mathematical methods to coax from photons a little more of a story about where they been and what they've seen.
A new system could also help troops identify radioactive and chemical threats.
The research program, called "Revolutionary Enhancement of Visibility by Exploiting Active Light-fields," or REVEAL, has two 24-month phases. The first would determine the limits of single-viewpoint scene reconstruction, while the second would create a framework for gathering more information from photons.
