Frequency Combs Enable Remote 3-D Mapping

Facebook X LinkedIn Email
A laser-based imaging system can now create high-definition 3-D maps remotely, with the ranging accuracy made possible by frequency combs. A team at the National Institute of Standards and Technology demonstrated the imaging system, which can create the 3-D surface maps from as far away as 10.5 m. Using lidar, the new system is also sensitive enough to detect weak reflected light. The frequency combs were previously demonstrated at NIST, but are now being used to continuously calibrate the laser imaging system. The system operates on a principle similar to optical coherence...Read full article
