A new laser camera created by a team from Heriot-Watt University in Edinburgh is able to detect individual photos and can follow objects moving around corners – even when obscured from view. It is able to log the position of a photo at the equivalent of 20 billion frames per second.
It is thought that the device could be used in search-and-rescue missions or used by cars to detect incoming vehicles. The device works by firing a laser at the floor near the corner they are trying to see around and the ultra-sensitive camera is able to pick up the spherical “echo” of a few photons which would normally be too faint to pick up.
