A network of four single-pixel sensors has done what a 20-million-pixel digital camera cannot: create a three-dimensional image of an object.

Producing a 3-D image is not easy. Filming a 3-D movie, for example, requires two expensive cameras plus complex software that stitches 2-D images from the cameras together.

Physicist Baoqing Sun of the University of Glasgow in Scotland and colleagues accomplished the feat with a couple of cheap parts and equipment available in most high sc...
