Scientists in Glasgow have discovered a low-cost way to create 3D images.
Their system uses detectors which have a single pixel to sense light instead of the millions of pixels used in the imaging sensors of digital cameras.
The detectors can "see" frequencies beyond visible light, which researchers say could open up new uses for 3D imaging in medicine and geography.
They said the single-pixel detectors cost "a few pounds" compared to current systems, which cost "thousands".
It is hoped that the system's ability to senses wavelengths far beyond the capability of digital cameras and its low cost, could make it a valuable tool for a wide range of industries.
Researchers said possible uses could range from locating oil to helping doctors find tumours.
