Paper Abstract

The nascent field of indirect imaging is concerned with the recovery of information pertaining to objects that are beyond the line-of-sight (LoS) and hidden from view. Current approaches to indirect imaging are either limited in their ability to recover spatially resolved imagery (resolution of few centimeters at 1-meter standoff) or impose severe restrictions on the imaging geometry. The present work examines two approaches that recover spatial detail on hidden objects by exploiting spatial and spectral correlation in the light scattered by the objects. Experiments have demonstrated the ability to discern sub-millimeter spatial detail, on centimeter sized objects positioned 1-meter behind a wall.
