How do you take images so fast that you can see light travelling through air? How do you take pictures without using a camera? And how do you use the latest technology to look around corners and see objects hidden from view? These are the questions that researchers from Heriot-Watt University and the University of Glasgow - the Creative Cameras team - are investigating. Our research is focused on developing new strategies for imaging which allow us to see the world in a new perspective.

We are constantly capturing pictures with our digital cameras and mobile phones, but the images we capture are largely restricted to 2D, to visible wavelengths, and to long exposure times. Our research challenges what is possible with a camera.
Creative Cameras demonstrate technologies that enable us to video light travelling through air, take 3D pictures with a regular camera, and take images in the infrared part of the spectrum with a camera with only a single pixel.
One of the cameras that we demonstrate has two very special properties. The first is its sensitivity to single photons – each pixel is around ten times more sensitive than a human eye; the second is its speed – each pixel can be activated for just 67 picoseconds, that’s more than a billion times faster than you or I can blink. The camera allows us to film at the speed of light – we can video pulses of light as they travel through air. One application of this technology is looking around corners to see objects hidden from view.
