Optical distance measurement at record-high speed

http://ift.tt/eA8V8J Scientists have demonstrated the fastest distance measurement so far. The researchers demonstrated on-the-fly sampling of a gun bullet profile with micrometer accuracy. The experiment relied on a soliton frequency comb generated in a chip-based optical microresonator made from silicon nitride. Potential applications comprise real-time 3D cameras based on highly precise and compact LIDAR systems.
