LiDAR has been around since the 1960s and uses laser pulses to measure distance with great accuracy. The new study, led by Edinburgh’s Heriot-Watt University with scientists drawn from NASA’s Jet Propulsion Laboratory, MIT, and the University of Glasgow, added something that could obtain highly detailed 3D data from up to one kilometer away.

As reported in Popular Mechanics, the creation uses an ultra-sensitive sensor called the superconducting nanowire single-photon detector (SNSPD). The system, co-developed by NASA and MIT, can trace a single photon to an accuracy of 13 picoseconds (13 trillionths of a second). It can also see through fog and smoke and could have many applications including security, monitoring and remote sensing.
