Imaging System Creates 3D Pictures by Measuring Time

Very interesting,  uses for creating 3D awareness of sensors.   Once again neural networks being used to gather information about changes in input.

Researchers at the University of Glasgow in the U.K., the Polytechnic University of Milan in Italy, and Delft University of Technology in the Netherlands have developed a new method of imaging that uses artificial intelligence to create pictures by measuring time. The technology captures temporal information about photons, rather than their spatial coordinates, to make animated three-dimensional (3D) images. The tool could be used to give 360-degree awareness to cars, mobile devices, and health monitors. The researchers used a single-point detector to record how long it takes photons produced by a split-second flash of a pulse of laser light to bounce off an object; a neural network algorithm transformed the temporal data into 3D images. Said the University of Glasgow's Alex Turpin, "This is really just the start of a whole new way of visualizing the world using time instead of light."
