Over the past 10 years techniques have been developed which acquire images using light that has never interacted with the object. Such ghost imaging originally used quantum entangled light and we have employed these techniques to produce images from single photons.

More recently it has been recognised that classical light works too, where the light transmitted is of a known, but random, pattern. We use the light from a data projector and a single element photo diode to fully reconstruct the 3D profile of an object.
