A $500 “nano-camera” that can operate at the speed of light has been developed by researchers in the MIT Media Lab.
The three-dimensional camera, which was presented last week at Siggraph Asia in Hong Kong, could be used in medical imaging and collision-avoidance detectors for cars, and to improve the accuracy of motion tracking and gesture-recognition devices used in interactive gaming.
“In contrast, the new “nano-camera” probes the scene with a continuous-wave signal that oscillates at nanosecond periods. … meaning the camera can reach a time resolution within one order of magnitude of femtophotography…”
Well, six (decimal) orders of magnitude (between femto and nano), but who’s counting. 🙂
