CAMERAS: Time-of-flight camera sees around corners

摘要

First conceptualized by Massachusetts Institute of Technology (MIT; Cambridge, MA) researchers and reported on by Laser Focus World back in late 2010, an ultrafast camera that could potentially see around corners has now been experimentally demonstrated by members of the original research team at the MIT Media Lab. By using time-of-flight techniques and computational algorithms to decode diffuse reflections from a 3D object concealed around a corner, the streak-camera-based setup--similar to that used by the MIT Media Lab to create trillion-frame-per-second visualizations--is able to reconstruct the shape of the object.
