Researchers at the University of Edinburgh and Heriot-Watt University have created a sensor that can see around corners using lasers, high speed cameras, and some intense data processing. They can essentially turn a laser light source into a virtual mirror to look through.
Led by [Genevieve Gariepy], the team has been able to prove their research in a lab setting, and are now trying to refine it to work in the real world. While the animated image above makes the system seem rather simple, the tech behind it makes our heads hurt.
The timing measurement alone for the laser light to bounce off the hidden object and be reflected to where the camera can see it needs to be accurate down to the 500 billionth of a second (500 nanoseconds). Five hundred billionths.
