Can we see around obstacles from a single viewpoint?  We are using millimeter/THz waves to augment vision to non-line-of-sight (NLoS) areas. By understanding the interaction of THz waves with common building surfaces, we can inverse the propagation path and reconstruction images of both LoS and NLoS objects.  Being able to see around obstacles will enable applications in rescue and surveillance missions, autonomous navigation, simultaneous localization and mapping, and wireless communications.
