What’s Behind the Corner? Imaging System will Know

A time-of-flight imaging system enables the indirect observation of hidden scenes via computational back-projection. Applications for this non-line-of sight technology range from small scenes (e.g., robotic or laparoscopic surgeries), to intermediate scales (e.g., remote detection of individuals for disaster response and law enforcement), to very large scenes (e.g., aerial and satellite surveillance).

Possible applications of this technique range from seeing around corners in scenarios with only limited scattering, to imaging an object that is obscured by bulk scattering materials (e.g., tissue or fog).

The imaging system is under development, with the support of the NASA Innovative Advanced Concepts program, and of the US Defense Advanced Research Projects Agency under the Revolutionary Enhancement of Visibility by Exploiting Active Light-fields (REVEAL) program.
