The New Science of Seeing Around Corners | Quanta Magazine

Two Massachusetts Institute of Technology (MIT) professors have invested lots of time and effort investigating ?accidental cameras,? which are objects like windows, houseplants and corners that can create images, shadows or reflections that provide information about their surroundings. Experts were astounded by the applications of this knowledge, including experiments in which they reconstructed a room based on the shadows created by a houseplant. In another application, they measured the sonic vibrations on a plant?s leaves and used them to figure out what people were saying nearby.

  • As people try to see things that may be far away, an edge of something might get in their line of sight.
