The $500 camera that operates at the speed of light
Researchers at Massachusetts Institute of Technology (MIT) Media Lab have built a $500 (£312) camera that can operate at the speed of light.
The camera is based on Time of Flight technology in which the location of objects is calculated by measuring how long it takes a light signal to reflect off a surface and return to the sensor.
Using off-the-shelf parts for its construction, it is hoped that the camera will have important applications for the medical industry.
