Camera tracks hidden objects with centimetre precision

13 December 2015

Heriot-watt researchers have developed a camera and laser system that can locate hidden objects with centimetre precision and then track their movements.

The camera is a development of Heriot-Watt University’s Extreme Light group under the leadership of Professor Daniele Faccio. “The ability to detect the 3D shape of static, hidden objects has been demonstrated before, but the long acquisition time required by existing methods meant locating and monitoring the objects was a major challenge," says Professor Faccio.

“We can now track hidden objects in real time and we’re still making discoveries about how the light identifies the objects, and can picture them in considerable detail. We’ve already increased the distance from which the camera system will work, which is over several metres. We’re also focusing on how we could attempt 3D reconstruction of the objects captured by the camera.”

Watch the video for a full explanation of the camera's function and capabilities.

An article describing this work is published in the journal, Nature Photonics.
