Next-Gen Laser Radar (LIDAR) for High-Accuracy Applications

NIST Inventors
Ian Coddington and William C. Swann
This invention is a new kind of laser radar (LIDAR) that uses two special lasers called femtosecond fiber lasers. One laser sends out a signal, and the other helps detect the signal that bounces back from a target. It combines two types of measurements—time-of-flight and interferometry—to measure
